Wir depend on Standard and Wir Test depend on Wir</p> <ul> <li> <p>In Standard we have one CallableSub <em>Document Entry Process</em> and it call another callablesub <em>Handler Document Entry</em></p> </li> <li> <p>In wir, we override the <em>Handler Document Entry</em> to create Ivy Task (use Task Switch/UserTask) then open the HtmlUserDialog of Wir project. We use the overriding function from Ivy.</p> </li> <li> <p>Now we have the start link from Wir Test (actually no matter where we put the startlink, could be on Wir),and it call <em>Document Entry Process</em> from standard, then run the Overriding Process of <em>Handler Document Entry</em> on Wir. </p> </li> </ul> <p>But when the process hit to Task Element, it throw this exception:</p> <pre><code> ch.ivyteam.ivy.request.RequestException: ivy:error:system at ch.ivyteam.ivy.request.RequestException$RequestExceptionBuilder.build(RequestException.java:161) at ch.ivyteam.ivy.bpm.engine.internal.BpmEngine.handleNormalRequest(BpmEngine.java:195) at ch.ivyteam.ivy.bpm.engine.internal.BpmEngine.handleRequestWithinContext(BpmEngine.java:140) at ch.ivyteam.ivy.request.impl.ContextAwareRequestHandler.handleRequest(ContextAwareRequestHandler.java:32) at ch.ivyteam.ivy.system.task.internal.SystemTaskJob.executeProcess(SystemTaskJob.java:127) at ch.ivyteam.ivy.system.task.internal.SystemTaskJob.executeAsSystem(SystemTaskJob.java:92) at ch.ivyteam.ivy.system.task.internal.SystemTaskJob$1.call(SystemTaskJob.java:56) at ch.ivyteam.ivy.security.internal.SecurityManager.executeAsSystem(SecurityManager.java:1467) at ch.ivyteam.ivy.system.task.internal.SystemTaskJob.execute(SystemTaskJob.java:52) at ch.ivyteam.ivy.job.internal.JobManager$1.call(JobManager.java:267) at ch.ivyteam.ivy.job.internal.JobManager$1.call(JobManager.java:1) at ch.ivyteam.util.callable.ExecutionContextContainer$ContainerExecutionContext.call(ExecutionContextContainer.java:92) at ch.ivyteam.ivy.security.internal.SecurityManager.executeInContext_aroundBody0(SecurityManager.java:1519) at ch.ivyteam.ivy.security.internal.SecurityManager.executeInContext_aroundBody1$advice(SecurityManager.java:41) at ch.ivyteam.ivy.security.internal.SecurityManager.executeInContext(SecurityManager.java:1) at ch.ivyteam.util.callable.ExecutionContextContainer$ContainerExecutionContext.call(ExecutionContextContainer.java:88) at ch.ivyteam.util.callable.ExecutionContextContainer.executeInContext(ExecutionContextContainer.java:27) at ch.ivyteam.ivy.job.internal.JobManager.execute(JobManager.java:261) at ch.ivyteam.ivy.job.internal.Job.run(Job.java:83) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: BpmError ivy:error:system Unique ID: 155EDB7F283297EF Process Element: create task for Document entry &lt;155C371802ADDD14-f62&gt;

It is not allowed to create tasks in required projects or in overriding projects. This is as restriction by design.</p>Reto WeissFri, 15 Jul 2016 15:25:41 -0400https://answers.axonivy.com/questions/1894/can-not-create-task-inside-overriding-sub-process-because-of-illegalstateexception-on-taskswitch/1897
