Like demo code, we must prepare "vote1_ParticipatorCollection" and " vote1_ManualRate" params. So, i add a create event listener "xxx.UserTaskCreateListener" for this usertask. In this listener, i set params for the delegateTask of listener , but when i start a processinstance for this processdefinition, i receive a exception message for some var is not found. </SPAN><BR /><BR /><SPAN>Can someone explain to me for this exception and my code, thx.</SPAN><BR /><PRE class="language-none line-numbers"><CODE><BR />&lt;userTask id="vote1" name="vote1" activiti:assignee="${participator}"&gt;<BR />&nbsp;&nbsp;&nbsp;&lt;extensionElements&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;activiti:taskListener event="create" class="xxx.UserTaskCreateListener"&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;activiti:field name="interceptorStack"&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;activiti:string&gt;MultiInst&lt;/activiti:string&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;/activiti:field&gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;/activiti:taskListener&gt;<BR />&nbsp;&nbsp;&nbsp;&lt;/extensionElements&gt;<BR />&nbsp;&nbsp;&nbsp;&lt;multiInstanceLoopCharacteristics isSequential="false" activiti:collection="vote1_ParticipatorCollection" activiti:elementVariable="participator" &gt;<BR />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&lt;completionCondition&gt;${nrOfCompletedInstances/nrOfInstances &gt;= vote1_ManualRate}&lt;/completionCondition&gt;<BR />&nbsp;&nbsp;&nbsp;&lt;/multiInstanceLoopCharacteristics&gt;<BR />&lt;/userTask&gt;<BR /><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN></CODE></PRE></BODY></HTML> Fri, 20 Jun 2014 09:49:10 GMT impulsehu 2014-06-20T09:49:10Z A question about MultiInstance and Listener. https://connect.hyland.com/t5/alfresco-archive/a-question-about-multiinstance-and-listener/m-p/195651#M148781 According to the following bpmn code, I create a usertask node, and add a create event listener and a multiinstanceloop element.In BPMN2.0 , we all know that we need prepare some necessary params before create usertask at a multiinstanceloop task.
