Activiti Designer with eclipse 3.6.0. Using callActivity in the main process, like that:
First created the Process SUBPROCESS with all the .activiti and .bpmn20.xml files correctly.
The diagram of the main process works fine, BUT using the callActivity with the SUBPROCESS:
<callActivity id="callactivity2" name="mainProcess" calledElement="SUBPROCESS"></callActivity>
and try to open again the diagram , the next exception happens:
Could not open the editor: org.eclipse.emf.ecore.xmi.UnresolvedReferenceException: Unresolved reference 'SUBPROCESS'.
