Now, I'm wondering, why I can't see the elements from the measuermentEntities list in the Acitviti Explorer, instated I see only measurementEntities which probably represents the list reference. Secondly and more important, why can't I access the elements of the list? Can somebody tell me, how I need modify this expression: measurement.measurementEntities[0].value in order to access the elements in the list.</SPAN><BR /><BR /><SPAN>Many Thanks,</SPAN><BR /><SPAN>Marco</SPAN></BODY></HTML> Thu, 08 Nov 2012 15:51:26 GMT mrhu 2012-11-08T15:51:26Z Accessing object hierarchy in usertask via expession languag https://connect.hyland.com/t5/alfresco-archive/accessing-object-hierarchy-in-usertask-via-expession-languag/m-p/101931#M70845 Hi all,I'm trying to set a process variable inside a userTask via client application by using juel and pojos as follows:BPMN2.0 Snippet:&lt;activiti:formProperty id="weight"&nbsp; name="Weight?" activiti:expression="#{measurement.measurementEntities[0].value}" &gt; A client that externaly renders the cor Thu, 08 Nov 2012 15:51:26 GMT https://connect.hyland.com/t5/alfresco-archive/accessing-object-hierarchy-in-usertask-via-expession-languag/m-p/101931#M70845 mrhu 2012-11-08T15:51:26Z Re: Accessing object hierarchy in usertask via expession languag https://connect.hyland.com/t5/alfresco-archive/accessing-object-hierarchy-in-usertask-via-expession-languag/m-p/101932#M70846 <HTML><HEAD></HEAD><BODY><SPAN>It's pretty hard to understand what is going on.
