Static JSF pages not found after updating to 8.0.4 / 9.1.0

Lukas Lieb — Wed, 18 Mar 2020 03:02:35 -0400

Since 8.0 you can create static JSF pages. Those pages can be accessed directly via a URL without being in an an HtmlDialog context. And until 8.0.3 they were still located in the webContent folder.

Are you affected?

If you used static pages and you upgrade to 8.0.4 your page will no longer be found by the engine.

What have changed?

To improve security, we changed the location to webContent/view. This helps you to decide which pages should be static and can be accessed directly.

How should your webContent folder look like?

If you use static pages, you should have a view folder, and if not, please do not use this folder. Your structure could look like something like the this:

webContent
  - META-INF/
  - WEB-INF/
  - view/          (static JSF pages -> direct call possible)
  - includes/    (templates, dialogs, etc -> no direct call allowed)
  - resources/  (images, css, js, etc. -> no direct call allowed)

Additional info

If you use static pages, you should consider securing them with a login.

How to switch off validation for ajax call?

anhle — Wed, 11 Dec 2019 23:40:42 -0500

Hi Ivy Team

I have a autocomplete. The autocomplete is required field. In autocomplete. I have ajax to handle change event. When autocomplete changes, some fields will be updated below. But When I clear data from autocomplete. The message required is display and some fields are no more update. So I want to do validation only when a button is clicked which submits the form but not when autocomplete changes. How I can do this?

Note: I try using "immediate" attribute in ajax to switch off validation but it is not work.

<p:autoComplete id="select-vendor" 
                widgetVar="select-vendor"
                value="#{purchase.vendor}" 
                dropdown="true" 
                scrollHeight="400"
                completeMethod="#{tenderInformationBean.completeVendor}"
                var="vendor" 
                itemLabel="#{vendor.vendorName}" 
                itemValue="#{vendor}" 
                maxlength="50"
                converter="pojoConverter" 
                cache="true" 
                queryDelay="500"
                rendered="#{!tenderInformationBean.isVendorNotFound}" 
                binding="#{tenderInformationBean.vendorNameAutoComplete}"
                disabled="#{isReadOnlySupplier}" 
                forceSelection="true"
                requiredMessage="#{ivy.cms.co('/ch.ivy.addon.portalkit.ui.jsf/common/requiredFieldMessage')}" >

                <p:ajax event="change" update="vendor-information-fieldset" global="false"
                    listener="#{tenderInformationBean.onSelectVendorName(purchase)}" onstart="if(PF('select-vendor').panel.is(':visible')) return false;"
                    immediate="true"/>

                <p:ajax event="itemSelect" update="vendor-information-fieldset" global="false"
                    listener="#{tenderInformationBean.onSelectVendorName(purchase)}" />

                <f:validator validatorId="awsValidator" />

JSF resource caching in Designer?

Andreas Rusch — Mon, 04 Nov 2019 08:46:32 -0500

I'm facing a problem when I do testing of Html Dialogs in the Designer. It seems that some of the resources get cached so I don't see my changes. Everything works on the Engine, but the pages don't get update in the Designer.

Is caching for JSF pages enabled in the Designer and if yes, how can I disable it?

Why does the JSF not reload when changing code in Axon.Ivy Developer 7.0?

How to find the root cause of error 500, frequently occuring in the logs

SupportIvyTeam — Mon, 13 May 2019 07:02:36 -0400

Some of users of my wf-app seem to face an error 500 while working. The errors show a viewExpiredException as cause of the problem. Generally this points to a session timeout issue. But as the user fires several request within seconds it doesn't make much sense, that one of the requests should fail with error 500 while others can be served as expected.

Unfortunately the behaviour is not 100% reproducible on any dialog. The logs expose the problem for several users but there is no clear pattern to find out which behaviour leads to these errors. Do I have any chance to isolate the real issue behind these error 500 logs?

How can I create a custom tag in Ivy

tdtin — Mon, 14 Jan 2019 08:50:37 -0500

Hi Ivy Team, I'm managing to create a custom tag in JSF. But it seems not work. Do I need to do something more ?

This is my custom class


@FacesComponent(createTag = true, tagName = "helloComponent", namespace = "http://example.com/tags")
public class HelloComponent extends UIComponentBase {
  @Override
  public String getFamily() {
      return "Greeting";
  }
  @Override
  public void encodeBegin(FacesContext context) throws IOException {
      String message = (String) getAttributes().get("message");
      ResponseWriter writer = context.getResponseWriter();
      writer.startElement("p", this);
      writer.write("Messageeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee: " + message);
      writer.endElement("p");

  }
}

This is my xhtml view :

Support for @FacesComponent within an Axon.ivy project without putting jars into ivy/WEB-INF/lib?

Genzer Hawker — Tue, 23 Oct 2018 00:06:34 -0400

Hi Ivy Team

According to the Release Notes of Axon.ivy Engine

Changes in 5.0 (since product release 4.3.0.39578, 7.5.2012)
 * Issue #23896 (Feature): Support implementing JSF Converter in Xpert.ivy projects

Update Release 5.1.8.50190 (22.10.2015)
+ 24770 Feature     Respect @FacesValidator annotation

Changes in 6.0.0.50515 (since product release 5.1.0.46949, 12.9.2014) 24.11.2015
- Faces validator support

So @FacesConverter and @FacesValidator are supported in project-scoped since v5.x and v6.0.

Is it possible to create custom @FacesComponent in project-scope as well without the need of making JAR files and put it in ivy/WEB-INF/lib? on the latest version v7.0.x?

Problem with Facelet tag

dangnguyen — Fri, 17 Aug 2018 03:49:59 -0400

I created a facelet tag and faced the problem that ivy components can not be rendered. Following are the steps which I created and used facelet tag:

Create file template
Create file xml tag lib
Register the context-param FACELETS_LIBRARIES with xml file in web.xml config
Use the facelet tag on the page
Result

I realized that whenever I register the context-param FACELETS_LIBRARIES with xml file in web.xml config, the ivy components can not work. Do you have any idea for this problem?

Problem with handling exception by AjaxExceptionHandler

tam_nguyenvan — Wed, 08 Aug 2018 02:39:32 -0400

Hi all,

I faced a problem when trying to use AjaxExceptionHandler as follow link: https://www.primefaces.org/showcase/ui/misc/exceptionHandler.xhtml that the implicit object pfExceptionHandler was not updated automatically when exception occured. Even if I have tried with AjaxExceptionHandler in managed bean.

Like this:

AjaxExceptionHandler aeh = new AjaxExceptionHandler();
aeh.setType("ch.ivyteam.util.IvyRuntimeException");
aeh.setUpdate("exceptionInfo");
aeh.setOnexception("updateExceptionInfo();");

FacesContext context = FacesContext.getCurrentInstance();
context.getApplication().evaluateExpressionGet(context, "#{pfExceptionHandler}", ExceptionInfo.class);

but the exception content still not updated.

Does any body experienced with this?

Thanks, Tam Nguyen

How to access database in a faces Validator

wesing — Mon, 23 Jul 2018 23:32:38 -0400

Hi all, I am new to AXON IVY. Hope you can be patient with me.

I am trying to use that code here: https://answers.axonivy.com/questions/314/using-db-connection-from-pis (provided by Ivy Support Team) in a Java class in a CustomValidator class to look up a database table. Somehow I could not resolve the Ivy object.

I tried looking up getProcessEngineHook method in https://developer.axonivy.com/doc/latest/PublicAPI but the search doesn't return any results.

My codes as follows:

package trial.facesValidation;
import javax.faces.application.FacesMessage;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.validator.FacesValidator;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;
import  java.sql.Connection;

// To validate if Item Name already existed in Parts table in Database
@FacesValidator("trial.facesValidation.CustomItemValidator")
public class CustomItemValidator implements Validator {

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException 
    {
        //connect to the database
        Connection dbconnection = ivy.getProcessEngineHook().getDbConnection("TrialDBConn");

        try
        {
        // execute some sql queries
        } finally {
        // close the connection
              dbconnection.close();
        }

Does Axon Ivy support pretty URL?

Tuyen — Tue, 05 Jun 2018 00:04:35 -0400

I've been a beginner in Axon Ivy for more than 1 month.

One of my questions is how to make JSF's URL of Ivy more beautiful or at least, simpler. I already worked with something called pretty-config with JSF before, so. Does Axon Ivy support it and how can I integrate with Ivy?

Formular is loosing decimal point

SupportIvyTeam — Mon, 30 Apr 2018 04:29:13 -0400

After sending the form, the decimal point is lost. For example, 0,78 becomes 78

This happens whenever I map p:inputNumber to the data type java.lang.Number.

Session Fixation with Axon.ivy

Bao Tran — Wed, 03 Jan 2018 04:25:25 -0500

Hi everyone, as far as I can find, every time user logs in with IVY Portal, the session is kept (not renewed). You can check this via JSESSIONID. Thus, it leads to session fixation attack.
May Axon.ivy provide a mechanism to prevent this kind of attack? I am using Axon.ivy 6.3.0.
Thank you.

Best practices to reduce the memory that is used by a single Html Dialog?

SupportIvyTeam — Mon, 20 Nov 2017 07:54:54 -0500

We have a huge Html Dialog that uses around 80 MB memory per session on the engine side. The dialog is like a wrapper for the full application. It contains multiple tabs and modal dialogs <p:dialog />.

Why is this Dialog consuming so much memory? Are there any best practices to build lightweight JSF dialogs?

Can I reduce the session-views that are held in the engine memory?

SupportIvyTeam — Fri, 03 Nov 2017 04:49:22 -0400

The Axon.ivy ivy Engine caches 20 JSF Dialog views per session. As I have a huge dialog with lots of sub-Dialogs this consuming a lot of memory on the Engine. Can I somehow reduce the amount of cached views?

Default progress bar

Tano93 — Thu, 03 Aug 2017 01:20:15 -0400

Hello everyone, is there a way to change the default progress bar, because in one specific scenario i want to have different progress bar but not the default one?

This is the progress bar that i want to change:

I want to do it for only one scenario, when the user presses a button and should wait for some methods to be executed. I have checked from primefaces showcase they provide some progress bar but I can put it somewhere in the screen and it is always there its not like this one in the image which takes the whole screen(makes the screen darker while loading and it is not possible to press anything) Thanks :)

Start process of Ivycomponent in ManagedBean

docvominh — Thu, 06 Jul 2017 09:47:34 -0400

Hi everyone, I had a dialog, and an ivyComponent. component is included into dialog When i try to call process in Logic of Dialog like this, it work fine.

    FacesContext context = FacesContext.getCurrentInstance();
    ExpressionFactory elFactory = context.getApplication().getExpressionFactory();
    ELContext elContext = context.getELContext();
    MethodExpression methodExpression = elFactory
            .createMethodExpression(elContext, "#{logic.mainMethod()}", String.class, new Class[0]);
    MethodInfo info = methodExpression.getMethodInfo(elContext);
    methodExpression.invoke(elContext, new Object[0]);

But when i try to call componentMethod() in component logic, it show method not found error : method not found example.main.componentMethod().

Update : each dialog had it own ManagedBean, and i fail to call when i use component ManagedBean.

Seem like current context is not belong to component, have anyone meet this before ?

Thank you :)

How to insert jpeg images from CMS into JSF?

Bruno Bütler — Thu, 08 Jun 2017 08:36:05 -0400

Jpeg images from CMS are not displayed on jsf dialogs when using IE (Internet Explorer 11 and AxonIvy6.6). e.g <h:graphicimage name="/images/Sonne" library="ivy-cms" width="300"/>

This is not a problem with png images from cms, not if the jpeg images come from the webcontent folder and also not if other browsers like Firefox or Chrome are used.

Any recommendations?

hibanassar — Thu, 01 Jun 2017 03:27:46 -0400

I have accordion panel inside a form with tow button one for add tabs ,another for next.

<h:form id="form">            
    <p:accordionPanel  var="job" value="#{data.JobSet.toArray()}">
        <p:tab title="title">
           <p:outputPanel>
       <p:panelGrid>
        <p:outputLabel for="Company" value="Company"></p:outputLabel>
        <p:inputText id="Company" required="true"
         styleClass="inputFullWidth" value="#{job.name}"></p:inputText>

        <p:outputLabel value="Industry"></p:outputLabel>
        <p:inputText  value="#{job.industry}"></p:inputText>
      </p:panelGrid>
   </p:outputPanel>
   <p:commandButton  immediate="true"
       value="Delete"
       actionListener="#{logic.deleteJob(job)}" update="#{cc.id}:form"

        </p:tab>

    </p:accordionPanel>
    <div>
     <p:commandButton validateClient="true"   
      value="Add"  actionListener="#{logic.addPJob}" update="form" >
     </p:commandButton>

     <p:commandButton validateClient="true"
      value="Next" actionListener="#{logic.send}" update="form" process="form" />

How to inject custom exception handler into Ivy

vhsvuong — Fri, 10 Mar 2017 03:33:16 -0500

Hi ivy team,

Now, I need to use the component p:ajaxExceptionHandler which required to configure in faces configuration file (faces-config.xml).

When I looked at this file in Ivy designer, I saw that you have already declared your own custom exception handler as RuntimeLogExceptionHandlerFactory. And inside that class, you always return RuntimeLogExceptionHandler instance

Note: you can refer this link to take an example: https://wmarkito.wordpress.com/2012/04/05/adding-global-exception-handling-using-jsf-2-x-exceptionhandler/ Or primefaces user guide documentation in the 11.3 section (Exception handler)

How can I inject my custom exception handler for using the component p:ajaxExceptionHandler ???

Please help me ivyteam, thank in advance. :)

In my jar file, i need to access to ivy project class loader, so i have this line:

 ClassLoader cl = Ivy.request().getProject().getProjectClassLoader();

I have a interface in this jar so i need to get class loader to find which class (from ivy project) is implementing my interface (vis ServiceLoader)

I guess my jar is started before ivy initialize its environment. So how can i solve it ?

P/S: when i try to start some more times, my engine can start but this exception is quite annoying imo

Thanks

OutOfScopeException: Cannot access scoped

trungdv — Tue, 11 Oct 2016 04:12:15 -0400

Hi all I'm using ivy 6.3.0 with JSF + Primefaces, when i test my website with multiple users at the same time, i got this:

12:36:49.661 ERROR [ch.ivyteam.ivy.dialog.execution.jsf.error] [http-nio-8443-exec-393] [requestId=2235134]
  Error during rendering of html dialog
    com.google.inject.ProvisionException: Unable to provision, see the following errors:
    1) Error in custom provider, com.google.inject.OutOfScopeException: Cannot access scoped [ch.ivyteam.ivy.dialog.execution.DialogRuntimeManager]. Either we are not currently inside an HTTP Servlet request, or you may have forgotten to apply com.google.inject.servlet.GuiceFilter as a servlet filter for this request.

We also get this problem when i embed my page to another by using iframe

We don't use any api from com.google.inject, it could come from ivy library i guess.

Does anyone have any idea why this exception occurred? Thanks all

Have jstl error

hungnam — Tue, 27 Sep 2016 14:21:16 -0400

I am using ivy both 6.0 and 6.2, and I have a lot of error trace java.lang.NoClassDefFoundError: javax/servlet/jsp/jstl/core/Config I think it's because of missing jstl jar file in ivy engine. Is there any solution for that?
