reassign in console crashes
---------------------------

                 Key: JBPM-896
                 URL: http://jira.jboss.com/jira/browse/JBPM-896
             Project: JBoss jBPM
          Issue Type: Bug
          Components: Web Interface
            Reporter: Tom Baeyens
         Assigned To: Tom Baeyens
             Fix For: jBPM jPDL 3.2


i think it will probably appear after every reassign.  but in case that works, try reproducing with the following scenario:
1) start a new process instance
2) a start task instance was created for the start task
3) entered a couple of values
4) did Save and Close
5) then I was navigated to the next task
6) in that next task i did a reassign
then i got the following exception
