Hello, Is there any way to do syntax highlighting in ivyScript?

Elasticsearch fail because auto-conversion changes String values into Date

Adrian Imfeld — Wed, 31 Jul 2019 04:33:14 -0400

We get an error of the Elasticsearch by saving a BusinessObject over the ivy.repo with a field of type Map< String,String >.

Elasticsearch update index of document failed because of: {"root_cause":[{"type":"illegal_argument_exception","reason":"mapper [details.data.Value1] of different type, current_type [text], merged_type [date]"}],"type":"illegal_argument_exception","reason":"mapper [details.data.Value1] of different type, current_type [text], merged_type [date]"}

The problem ist clear. The field "details.data.Value1" is a date field and i try to store a String.

But the definition of our BusinessObject is different to that!
The field "data" of the "detail" object is defined as a Map< String,String >.
We get this error when we run the following code in an IvyScript (we used a helper class for Maps, because IvyScript is not able to handle double generics).

JobDetail detail = new JobDetail();
Helper helper = new Helper();
helper.setParam("Value1", (new Date()).toString());
detail.data = helper.getParams();
job.details.add(detail);

detail = new JobDetail();
helper.setParam("Value1", "foo");
detail.data = helper.getParams();
job.details.add(detail);

Why does Elasticsearch change the given attribute to a date field, although we just fill in String values?
Furthermore we defined the value as a Map of Sting-String value pairs.
Is there a solution of this issue?

We decided not to use JSON objects instead of our Map, because of the easy handling in further uses.

How can I set a Task with dynamic name by Ivy script

Hi there. Today, I have a problem with the name of a task. The first time, when I create a task with a name ABC, after do something, it changes XYZ. I changed the task name by Ivy script, like this:

My problem is now, the task name can't be changed reply on the locale. My question is How can I use cms to set for a dynamic name for Task and then let it resolves by CMS?

How to properly integrate and deploy a third-party library in an ivy project and deploy it to the engine?

LaAck — Fri, 03 Nov 2017 08:56:59 -0400

Hi,

we've modeled a process where some IvyScript tasks make use of a third-party library. For usage in the ivy Designer we just added it to our ivy project and it worked. But whenever we try to deploy everything to the engine we get an error which says that a class from the mentioned library is not available.

Hence, my question is: What is the standard workflow to integrate and deploy third-party libraries properly? Do we have to add them manually to some special engine folder (I'm just wondering because I've found some lib folders)?

Thank you very much in advance and kind regards, Lars

What is the right way to check the OS where ivy is running?

Stelt0 — Fri, 02 Jun 2017 03:11:20 -0400

Hello Ivy Team,

I`m wandering what is the best practice(if any) to check what is the operating system where Ivy is currently running (i.e. Windows 10, Windows Server 2012, Linux, MacOS, etc..)

How to debug Ivy Script?

RemiMorin — Mon, 14 Nov 2016 20:41:45 -0500

Hi, I'm currently extending a existing Ivy application. I face the problem of being unable to debug (trace) Ivy script.

Is there some tooling? maybe some trick to output directly into the "runtime log" of the designer?

I've already hack the logger to display SQL and such. I'm familiar with web development, java, tomcat and most of the ecosystem. I just have hard time tracing the logic in process. I currently have a bug with Ivy add on, I replace all parameter values one by one with hardcoded values to see what is going on. I've figure out which variable is erroneous but can't figure out what's in it.

IvyScript - support for Streams and Lambda expressions

Stelt0 — Mon, 18 Jul 2016 13:22:42 -0400

Hi All,

I see that IvyScript does not support some of the new features in Java8 like Streams and Lambda expressions. Is it in the road-map ?

Inconveniences when using inner classes in Ivy Script

Genzer Hawker — Fri, 29 Apr 2016 07:13:17 -0400

Suppose I have two classes, each of them provides Builder API.

// This is in Ivy Script
import example.Person.Builder;

Builder errorPersonBuilder = new Person.Builder(); // this line generates a compilation error saying class Person.Builder not found.

Builder workingPersonBuilder = new Builder(); // this works.

It is still OK if there is only one Builder inside the context. As soon as there is another:

// This is in Ivy Script
import example.Person.Builder;
import example.Company.Builder; // compilation error of collision, there are two classes named Builder.


Builder workingPersonBuilder = new Builder(); // this works, see above.

Builder anotherBuilder = new Builder(); // which builder?

If Ivy Script could supports the same as normal Java, we could do:

import example.Person.Builder;
import example.Company.Builder;

Person.Builder personBuilder = new Person.Builder();
Company.Builder companyBuilder = new Company.Builder();

Should this be supported in Ivy Script?

How to use content with contents in ScriptSteps?

Adrian Imfeld — Tue, 28 Jul 2015 11:36:32 -0400

I have a Label (cms content) which holds other labels. The content of my label looks like that:

<%=ivy.cms.co("/Labels/Labels/username")%> or <%=ivy.cms.co("/Labels/Labels/password")%> is incorrect.

It works fine in JSF UI's with this code:

"#{ivy.cms.co('/Labels/Messages/loginFailedMsg')}"

But if I fill a process variable over a ScriptStep like this...

out.message = ivy.cms.co("/Labels/Messages/loginFailedMsg");

... the integrated contents are not rendered.

Is there a way to get the fully rendered label in a ScriptStep?

List converted from an Enum array in Ivy Script doesn't work correctly

Genzer Hawker — Thu, 12 Mar 2015 08:27:40 -0400

Today I found something looks like a bug in Ivy Script.

In Ivy Script, I want to have a List of all the elements of an enum, say WorkflowPriority, I simply call WorkflowPriority.values(). However, the instance of List returned by the call doesn't work correctly, especially with operation contains and remove.

Here are the tests that I made to check:

(This is an Ivy Script snippet)

import org.junit.Assert;
import com.genzerhawherk.bugs.Lists;
import ch.ivyteam.ivy.workflow.WorkflowPriority;

// Below are all failed tests
Assert.assertTrue(WorkflowPriority.values().contains(WorkflowPriority.HIGH));

List<WorkflowPriority> withGenerics = WorkflowPriority.values();
Assert.assertTrue(withGenerics.contains(WorkflowPriority.HIGH));

List fromEnums = Lists.fromEnums(WorkflowPriority.class);
Assert.assertTrue(fromEnums.contains(WorkflowPriority.HIGH));

List fromEnumVarargs = Lists.enumVarArgs(WorkflowPriority.HIGH, WorkflowPriority.EXCEPTION);
Assert.assertTrue(fromEnumVarargs.contains(WorkflowPriority.HIGH));

// Below are all passed tests
List listComprehensive = [WorkflowPriority.HIGH];
Assert.assertTrue(listComprehensive.contains(WorkflowPriority.HIGH));

List newPriorities = new List().addAll(WorkflowPriority.values());
Assert.assertTrue(newPriorities.contains(WorkflowPriority.HIGH));

List fromList = Lists.toArray([WorkflowPriority.HIGH]);
Assert.assertTrue(fromList.contains(WorkflowPriority.HIGH));

List fromVarArgs = Lists.normalVarArgs(WorkflowPriority.HIGH);
Assert.assertTrue(fromVarArgs.contains(WorkflowPriority.HIGH));

List<WorkflowPriority> manuallyConstructed = new List<WorkflowPriority>();
manuallyConstructed.add(WorkflowPriority.HIGH);
Assert.assertTrue(manuallyConstructed.contains(WorkflowPriority.HIGH));

The bug particularly relates to converting <T extends Enum<T>> T[] into a List<T>

Below is the class Lists I use in the test

public class Lists {

    public static Object[] toArray(Collection<?> collection) {
        return collection.toArray();
    }

    @SafeVarargs
    public static <T> T[] normalVarArgs(T...elements) {
        return Arrays.copyOf(elements, elements.length);
    }

    public static <T extends Enum<T>> T[] fromEnums(Class<T> enums) {
        return enums.getEnumConstants();
    }

    @SafeVarargs
    public static <T extends Enum<T>> T[] enumVarArgs(T...enums) {
        return enums;
    }
}

How to dynamically open tab which binds a ivycomponent?

nwk2Team — Thu, 05 Mar 2015 11:01:22 -0500

My team got some problems with adding a new p:tab which contains ivycomponent. In the first tab of the p:tabview contains a p:datatable. A new p:tab should created/opened each time if the user clicks a row in the datatable.

In the new p:tab should include a ivycomponent with 2 parameters, which looks like following:

Has anyone already gained experience with loading ivycomponent(s) within a dynamic p:tab? Thank you for sharing!

Kind regards

Chaining checking for initialization in Ivy Script

Genzer Hawker — Mon, 04 Aug 2014 11:35:59 -0400

In the Ivy Designer Guide, Chapter 7, section Null handling / Automatic object creation, it states

You can to use the .# operator to suppress the automatic object creation.

if( in.#customer == null)
{
  // object is null
}

if (in.#customer is initialized)
{
  // object is not null or has been set to a non-default value
}

I also discover that we can do a chain of suppresing initialization like this:

if (in.#bigDataClass.#smallerDataClass.#smallDataClass.#tinyDataClass.#fieldXyz is initialized) {
    // Reach here if all of the properties are initialized
} else  {
   // Reach here if any of the properties are null
}

This really reduces the verbosity of the code when I want to check a deep structure of data classes. Despite its usefulness, I cannot find any (Ivy) documentation mentioning about this feature. I only discovered it by chance and have been using it until now.

My question is whether this is an official feature but has been forgotten to mention or it is an unofficial/hidden feature and could be dropped in the future?

Thanks & Regards

Error on creating a typed Map in Ivyscript (Ivyscript and Generics)

Barbara Brugger — Wed, 23 Jul 2014 16:44:16 -0400

If I create a typed Map in a script step, (e.g. Map<Integer, String> map = new HashMap<Integer,String>();) I get the error "Unexpected token: ','".

Nevertheless the code compiles and the process can be executed. Why does this error appear on the script step?

How to resend task notification e-mail?

Timo Rupp — Tue, 20 May 2014 19:02:54 -0400

When a new task is created, Xpert.ivy sends a notification email to the asignee. This is of course based on some configuration stuff.

I change the assignee of an existing task programatically (with public workflow API). Now I want the new assignee to get the task email. Is it possible to trigger this email again for some ITask?

A workaround would setting the existing task to SYSTEM user and implement a loop in the business process to create a new task. This causes some side effects, that are not acceptable in my scenario.

Deserialization of Java Bean not possible within an ivy Script Element

Stefan — Mon, 24 Feb 2014 14:24:39 -0500

ivy 5.0.9

I created an Helper Class which should serialize / deserialize a Java Bean with the java.beans.XMLEncoder / XMLDecoder Class. Serialization works great, but if I want to deserialize the xml string within an Ivy Script Element, I got the following Error: java.lang.ArrayIndexOutOfBoundsException: 0

If I do the deserialization within the Helper Class itself (as described as follows), the deserialization works great. Is there a way to bring it working within the Ivy Script Step?

Thanks in advance for your ideas...

Helper Class "decode"

public Employee decode(String xml) {
    try {           
        XMLDecoder decoder = new XMLDecoder(IOUtils.toInputStream(xml, "UTF-8"));
        Employee employee = (Employee) decoder.readObject();
        decoder.close();
        return employee;
    } catch (Exception ex) {
        Ivy.log().error(ex.getMessage(), xml);
        return null;            
    }                       
}

Calling the method using Ivy Script Step (Not working)

import test.XmlHelper;
import test.Employee;
try {
    XmlHelper xh = new XmlHelper();
    in.employee = xh.decode(in.usrData); 
    /*
    (in.employee is a DataClass Attr. of type Employee
    in.usrData is a DataClass Attr. of type String containing the xml String)
    */
} catch (Exception ex) {
    in.errmsg = ex.getMessage();
}

Calling the method directly in the Helper Class by main method (Works great)

public static void main(String[] args) {        
    XmlHelper xh = new XmlHelper();     
    Employee employee = new Employee();
    employee = xh.decode("<java version='1.7.0_17' class='java.beans.XMLDecoder'><object class='test.Employee'><void property='firstName'><string>Vorname</string></void><void property='lastName'><string>Nachname</string></void>");
    System.out.println(employee.getFirstName());
    System.out.println(employee.getLastName());

}

Bean Employee (in ivy located under /src/test/entity )

package test.entity;

import java.io.Serializable;

public class Employee implements Serializable {         
private static final long serialVersionUID = 1L;
private String      lastname        = "";   
private String      firstname       = "";   
public String getLastName() {
    return lastname;
}
public void setLastName(String lastname) {
    this.lastname = lastname;
}
public String getFirstName() {
    return firstname;
}
public void setFirstName(String firstname) {
    this.firstname = firstname;
}

}

Generic classes in ivyscript

Alexis — Wed, 19 Feb 2014 13:18:14 -0500

Hello IvyTeam

Is there a simple way calling self made generic classes? Like the List.

Data:
dao Dao<item>

in Ivyscript:
calling dao.get(id) the response would be of type Item.

generic Class:
T get(int id)

It would be great if there is a solution.

Thanks for an answer and Greetings

Edit: Trying to extend a class with the Generic doesn't help any further.
In java code those objects return items as it should and in ivyscript Objects are still returned.

public class DaoItemTest extends Dao<Item> {
    public DaoItemTest() {
        super(Item.class);
    }
}

How to reset permissions of an user or role?

Flavio Sadeghi — Fri, 08 Nov 2013 11:36:01 -0500

In our project we set specific permissions to the application users and/or groups. Now we have the requirement to reset them to the default permissions.

Is there a functionality directly in the UI or exists a public API?

How to work with java.util.Date in IvyScript-Step without auto initialization

Adrian Imfeld — Wed, 06 Nov 2013 14:42:43 -0500

In an IvyScriptStep variables are auto initialized as soon as they are accessed. The following code will log "bad":

java.util.Date date = null;
if ( date!=null) {
    ivy.log.info("bad");
} else {
    ivy.log.info("good");
}

It looks like the object "date" will never be a java.util.Date, it is an IvyDate. There is also no chance to import java.util.Date because of a conflict.

How to convert a List to a Recordset?

Flavio Sadeghi — Thu, 31 Oct 2013 14:30:22 -0400

When migrating projects from version 3.x to 4.x or 5.x some APIs has changed and calls has to be rewritten.

In versions > 4.x most APIs returns List, however similar APIs in 3.x returns Recordsets.

Therefore, what is the easiest way to convert a List (of a specific type) to a Recordset, so that I only has to change the calls and I do not have to touch the existing process?

Switch Case statement in ivyScript

Lars Winnat — Thu, 10 Feb 2011 05:53:24 -0500

I would like to use switch case like I can use it in Java in ivyScript. But I get validation errors if I use it. Do I have to take care about a special syntax?

Casting in ivyScript

Dirk Busmann — Thu, 18 Mar 2010 08:48:28 -0400

I need to call a method on certain componentes within a rich dialog panel. I get all components of the panel and then loop over them like this:

List<ULCComponent> listComponent = panel.getComponents();
for(int i = 0; i < listComponent.size(); i++){
    if(listComponent.get(i) instanceof RLabel){
        RLabel label = (RLabel) listComponent.get(i);
        ((RLabel) listComponent.get(i)).setVisible(in.showLabel);
    }
}

In both lines with the casting I get exceptions:

Unexpected token: identifier 'listComponent'

What is wrong?
