nndiem — Thu, 11 Jun 2020 06:19:42 -0400

Hi, ivy team support, May we ask you what is the way ivy server build process model name and put it inside table iwa_processmodel?. I saw sometimes it is uppercase, sometimes it is lowercase.

Thanks

Error on calling trigger

a_v_a — Wed, 01 Apr 2020 05:31:22 -0400

Hello all,

We have the following error when calling a trigger: The process works perfectly fine on the designer, but on the engine it throws this error. We use engine version 8.0.2. Any ideas what might be the cause and eventually the solution?

Thanks, Alex

Exception when calling sub process on java

nvcuong01 — Wed, 04 Dec 2019 05:58:36 -0500

Hi guy,

I am using java to call a sub process (1). On sub process, it calls another process on async mode and wait for this async process finished. But it gets an exception

ClassCastException: java.lang.Object cannot be cast to ch.ivyteam.ivy.scripting.objects.util.IIvyDataObject BpmError: ivy:error:system IvyRuntimeException: BpmError ivy:error:system Unique ID: 16ED0879C1F1D89D Process Element: Wait for the other business processes to end <16ECF9C19BDDE0E4-f6> Process Call Stack: callServiceCheck() <16ECF9C19BDDE0E4-f0> ch.ivyteam.util.IvyRuntimeException: BpmError ivy:error:system Unique ID: 16ED0879C1F1D89D Process Element: Wait for the other business processes to end <16ECF9C19BDDE0E4-f6> Process Call Stack: callServiceCheck() <16ECF9C19BDDE0E4-f0>

But it can work well if I trigger the start link (2) directly

How can I overcome this problem?

Thanks!

How to set multiple responsible roles for a process start request

Adrian Imfeld — Thu, 07 Nov 2019 09:49:11 -0500

How can we set more than one role as "Responsible role" on a Request Start element on the Request tab. Users with different roles (not able to organize under one commen role tree node) should see a process in the portal and should be able to start it.

My workaround at the moment is to define two different start elements, which are identical except the responsible role. It works, but... If one user holds both roles, he will see two identical processes.

Thanks for help.

Java Api for Start Process Signature variables

Stelt0 — Tue, 17 Sep 2019 09:38:57 -0400

Hello IvyTeam,

Is there a way to get the list of parameters which are defined in the Signature of a process start element ? *I need this information before starting the process instance.

I checked the public API but such information is not available. So, I assume there is an Internal API that I can use ? Can you provide some code snipet?

Best Regards, Yordan

Show process model as header doesn't work

jan dietsche — Mon, 18 Jun 2018 12:05:10 -0400

We want to show the name of the process model with <h:outputText value="#{ivy.request.processModel.name}"> but the variable is empty.

Ivy Process Start parameters Encoding

Emmanuel Comba — Tue, 29 May 2018 07:04:59 -0400

Hello IvyTeam !

Sometimes Ivy Processes are called via their url in a browser and we set some params as URLEncoded Parameters. Example : firstname=Élisabeth and lastname=Müller http://comba:8081/ivy/pro/designer/services_mock/162D9B06E7844FCB/videoIdentification.ivp?gender=Frau&firstname=%C3%89lisabeth&lastname=M%C3%BCller

In that case we have to encode the url parameters with "ISO-8859-1" charset which is the IVY default encoding. Is that possible to change this to "UTF-8"? Shouldn't Ivy set the default encoding to "UTF-8"?

This has been tested with Ivy 7.0.4.

Thanks a lot in advance Cheers Emmanuel

How to quick search for some text in a mod file?

Emmanuel Comba — Thu, 17 May 2018 10:47:34 -0400

Hello IvyTeam,

We need often to search for some code snippet in some big Ivy Process files (.mod). We can do it in the text editor but it is not very handy to change anything there. The best would be to search with CTRL+F for some text. Then the designer should highlight the Steps where this text has been found. This would be a great help for our productivity.

Do you plan to do such an improvement?

Thanks in advance Emmanuel

How to get the URL of a process start within a JAX-RS class

Emmanuel Comba — Wed, 18 Apr 2018 15:06:23 -0400

Hello IvyTeam,

My Ivy Version : 7.0.3 I would like to get the url from a process in a JAX-RS Rest Resource but I get an Exception with this code:

Ivy.html().startref("Functional Processes/dis/videoIdentification/start.ivp")

The JAX-RS Resource is located in the same project as the process. It works without problem in a Process (IvyScript Step).

I can imagine that the fact the code is in a JAX-RS Resource does not allow accessing some Ivy resources like the ProjectModelVersion Provider. Is there a workaround for that? Or do I have to compute the url more manually with the InetAddress and so on ? By the way this code works in this resource: Ivy.html().applicationHomeRef()

Thanks in advance

Period for ivy processes with UI

dolong — Sun, 26 Nov 2017 23:53:25 -0500

I would like to set the period to run any ivy processes with UI. Is there any ivy API to support it without adding the "Program start" element to processes? If not, is there any way to start a process (not callable process) in Java?

How to change stage inside case map?

adamf — Wed, 27 Sep 2017 09:54:22 -0400

I have a case map project with 3 stages, each having one process. It should be possible to jump from first process to last stage.

Inside scirpt I call

ivy.case.getBusinessCase().setStageId(stageIdStr)

But get error:

IllegalStateException: Only business cases with no active sub cases can be finished
Could not handle case map event 'STAGE_CHANGED' for business case '4'

Because I am inside the process my case is still active.

Summary: As Pointed out in the answer, this error can be ignored and only triggers when after changing stage all processes are finished.

End Page on User Dialog

Stelt0 — Tue, 26 Sep 2017 04:27:51 -0400

Hello Ivy Team,

I have a business process starting with an User Dialog, where the user can submit a request. After that the process is doing a lot of background activities and it is assigning tasks.

The application is part of the Portal application. Currently, when the user submit the request, he is redirected to the Task List of the Portal.

Is it possible instead of redirecting int to the Task List, to show him some Thank You page ? The problem is that this process can be started by users that does not have Ivy user and in this case he is redirected to the Portal Login page. For these users this makes no sense.

Best Regards, Yordan

Difference between Email.Server.MailAddress & Email.Server.User?

ToanLC — Thu, 27 Jul 2017 07:03:36 -0400

Hi guys,

Recently I come to wonder what's the difference between the two configuration of email.

EMail.Server.MailAddress
EMail.Server.User

As I saw that when I try to send mail using email element in process, I specified the "From" field, but it sent the mail using the one I specified at EMail.Server.User.

Could you help me differentiate these fields as their purposes? May I have some thing wrong in the configuration?

Detecting when the user closes the window or tab of the browser in a Html Dialog

Jailson Brito — Mon, 30 Jan 2017 23:51:34 -0500

Hello! I have the following scenario:

User goes to the their Personal Task List;
There's 1 task;
User closes the window or tab in the browser;
User comes back in 5 minutes and goes to their Personal Task List;
The task is gone;
After 30 minutes, the user refreshes the page;
The task is back;

Question 1. I understand that since the user started to work on that task (step 2), it changed from SUSPENDED to RUNNING, and other users are not able to see that task in the meantime. I don't understand why even the user that is working on that task, can't see the task in the Personal Task List.

Question 2. Using Html Dialog, How to detect when the user change the context on the browser, to bind it to an event in the Logic? For example, if the user closes the tab/window, then it would fire a process to change the task to SUSPENDED again.

I found old answers but they don't seem to be the exact scenario:

Hook into global closing with "X" on the window - It talks about Rich Dialog and Java Class, I am using Html Dialog and I would like to bind it to an event containing a Script Step with a code in Ivy Script;
How can I logoff the user if he closes the browser? - This one says that the task would be immediately available for the same user, but this is not what's happening in my scenario.

Thanks in advance.

TaskState after sending redirect

trungdv — Thu, 29 Dec 2016 05:04:17 -0500

Hi all

i have a sample process like this: In there i have a ivy task, after i close user dialog, i want to redirect to another start process by using HttpResponse (not use endpage element). With some small investigation i see the task state after i send redirect still be RESUMED,

If i change this process to continue with endProcess element (after script httpRedirect), it throw exception:

So, to deal with this case, i need to reset task manually?

How to get BpmEngine belong to a Process Model Version

trungdv — Wed, 28 Dec 2016 02:52:32 -0500

Hi all, in module A, I have a function that return a BpmEngine as:

IBpmEngine engine = DiCore.getGlobalInjector().getInstance(IBpmEngine.class);

With this line of code i get instance which belong to module A somehow.

Now i also want to get IBpmEngine from other related modules (example: my module A depend on module B). I check the code then see each BpmEngine has a different id, combine between project model name and project model version: (class ch.ivyteam.ivy.bpm.engine.internal.BpmEngine)

this.id = "BPM engine " + this.getProcessModelVersion().getApplication().getName()
                + "/" + this.getProcessModelVersion().getVersionName();

Is there anyway to get BpmEngine of other related modules?

P/S: somehow this question is related to this post where i want to register listener for other module.

Eager Loading

Stelt0 — Wed, 21 Dec 2016 09:19:58 -0500

Hello Ivy Team,

In my project, I had to switch from the default Eager loading to the Lazy loading of the Entity classes. The reason was that the queries were not optimized. Now I have the following problem, every time I try to inspect the variables in debug mode, the Designer is throwing errors and it is almost impossible for debugging:

Startref Issue

dharlach — Wed, 31 Aug 2016 12:49:51 -0400

We're facing following Issue:

Could not find a start with name '15601A89E0030024/Logout.ivp'

We tried following ways:

{ivy.html.startref('Start Processes/Home/Logout.ivp')}

{ivy.html.startref('15601A89E0030024/Logout.ivp')}

The problem is, that the Logoutprocess is in another Project which is in the required Project list of the Projects which tries to start the logout process.

How can we fix that?

Regards, Dani

Trigger activity - no task

Stelt0 — Wed, 20 Jul 2016 07:48:50 -0400

Hello All,

I have a HTML Dialog. In the Logic I use the Trigger activity to call a Business Process. It works, but it creates a task.

Is there a way to be invoked immediately and not create and assign a task ? My process is pure server-side logic.

How to solve Tomcat 302 error problem?

We try to call an IVY process start link (/ivy/myprocess.ivp?id=213214) by an external application. As response we expect a JSON object.

But it seems that the IVY Tomcat redirect our request (error 302), so we do not get the response back. Does anybody know to solve this problem?

How to resume a process instance

potea — Sun, 03 Apr 2016 11:52:05 -0400

Hello,

how can I resume a process instance? E.g. a user exits a process before the process is ended. How can I display a overview of the not finished processes and let him or another user in a certain role resume at this specific point?

Thanks!

500 Server Error when hitting history back button of browser

Marcel von Wyl — Wed, 26 Aug 2015 08:47:31 -0400

I have the problem, that if you have two or more dialog calls in a process, you cannot use the history back button of the browser, as soon as you are past the first dialog.

In this example, as soon as you reach Education, it does not work anymore.

I think the reason for this is, that the dialog instance is closed, when you leave a dialog and move further (Dialog Close event).

I think that this is ivy specific, becuase as far as I know, it works properly with plain PF/JSF. In my opinion, the back button should work allways, becaus of the usability, and the developer should take care of what happens with data and so on.

Anyway, does anybody have a solution for this?

Listen to process-case start and task creation & start

Emmanuel — Tue, 03 Mar 2015 17:07:50 -0500

I would like to know if there is a possibility to dynamically listen to all ivy standard processes starts and ivy task creations and starts. The idea would be to get a reference to any standard processes-cases that are started or tasks that are created.

Thanks a lot in advance

How we can obtain the context of the business process programmatically?

Genzer Hawker — Mon, 02 Mar 2015 10:56:42 -0500

We want to implement a feedback feature in which the user can submit a feedback at any where. What we want to achieve is to attach the context (what is the current screen, which point in the process, etc) into the feedback.

I found out a way to (somehow) close to what we expect:

StringBuilder fullContextBuilder = new StringBuilder();
for (IIvyThreadLocal threadlocal : IvyThreadContext.getIvyThreadLocals()) {
    fullContextBuilder.append(threadlocal).append("\n");
}
Ivy.log().error(fullContextBuilder.toString());

However, the IIvyThreadLocal and IvyThreadContext are not @PublicAPI so we could not rely on them.

Is there a public API which can help me to obtain the context of the business process (something like what printed in the log file for an exception)?

UPDATE

(It seems I was still ambiguous about what the process context mean)

The process context here means what is the current dialog and the context when the feedback submittet. What is the route (dialogs to dialogs) that the user has accessed before submitting the feedback.

The idea is something similar to what is printed in the Ivy Server log file. I started to digg into the Logger and ExceptionUtil which I experimented as the snippet above.

Thanks & Regards
