https://answers.axonivy.com/questions/1905/trigger-activity-no-task<p>Hello All,</p> <p>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. </p> <p>Is there a way to be invoked immediately and not create and assign a task ? My process is pure server-side logic.</p> <p>Best Regards, Yordan Yunchov</p>enTue, 28 Feb 2017 10:07:47 -0500https://answers.axonivy.com/questions/1905/trigger-activity-no-task/2470<p><strong>Scenario</strong><br> - Process A has a HTML dialog <br> - Process B has a task switch<br> - If user click a button in HTML dialog, it will trigger process B. =&gt; 1 case of process A and 1 case of process B is created. We do not need the case of process A. <br> How can we implement without creating the case of process A.<br></p> <p>I follow the guideline of Reguel, inside the callable process I have a task switch. It leads to the error like this:<br></p> <pre><code>Caused by: java.lang.IllegalStateException: TaskSwitch element (Role Approval &lt;15A82F10A6717E03-U60-f28&gt;) is not permitted inside a sub process that was invoked from a User Dialog process. at ch.ivyteam.ivy.bpm.engine.internal.model.bpmn.TaskSwitchElementExecutorAdapter.checkIllegalTaskSwitchUsage(TaskSwitchElementExecutorAdapter.java:105) at ch.ivyteam.ivy.bpm.engine.internal.model.bpmn.TaskSwitchElementExecutorAdapter.execute(TaskSwitchElementExecutorAdapter.java:81) at ch.ivyteam.ivy.bpm.engine.internal.model.ProcessElement.lambda$0(ProcessElement.java:215) at ch.ivyteam.ivy.bpm.engine.internal.model.ProcessElement.executeInElementContext(ProcessElement.java:286) at ch.ivyteam.ivy.bpm.engine.internal.model.ProcessElement.execute(ProcessElement.java:215) at ch.ivyteam.ivy.bpm.engine.internal.core.ProcessElementExecution.execute(ProcessElementExecution.java:37) </code></pre> <p>Is there a way to trigger another business process (by using Trigger, Signals, Callable sub,...) from a HTML dialog without persisting the ICase of the current business process?</p> <p>Thanks and regards,<br> Tung</p>lttungTue, 28 Feb 2017 10:07:47 -0500https://answers.axonivy.com/questions/1905/trigger-activity-no-task/2470https://answers.axonivy.com/questions/1905/trigger-activity-no-task/1908<p>If you don't want a task and an asynchronous execution then a Callable Sub Process could do the job better. Just put your target process logic in BPM process of kind 'Callable Sub Process' and invoke it from the Html Dialog by using the (Subprocess) 'Call' Activity.<img alt="alt text" src="http://answers.axonivy.com/upfiles/callableSubProcessCreation.png"></p>Reguel WermelingerThu, 21 Jul 2016 08:51:39 -0400https://answers.axonivy.com/questions/1905/trigger-activity-no-task/1908
