      Hello everyone

      I want my main process to end if the subprocess returns a certain result. If the subprocess is followed by an "end" element the following Exception is thrown:

      You can test this using the org.jbpm.examples.subprocess.outcomeactivity test case.
      Change the following: 

      <process name="SubProcessDocument" xmlns="http://jbpm.org/4.0/jpdl">

 <start g="32,111,48,48">
 <transition to="review" />
 </start>

 <sub-process name="review"
 sub-process-key="SubProcessReview"
 g="96,16,127,52">

 <transition name="ok" to="next step" g="167,67:6,-19"/>
 <transition name="nok" to="update" g="-22,-18"/>
 <transition name="reject" to="close" g="167,200:7,3"/>
 </sub-process>

 <state name="next step" g="255,41,88,52"/>
 <state name="update" g="256,106,88,52"/>
 <end name="close" g="258,175,88,52"/>

</process>


      The last element is changed from a "state" to an "end" element.

      Well is this constellation conceptional not possible or should I file a bug?

      cheers
