      Hi,

      After upgrading JBoss jBPM JPDL designer from 3.1.0.GA to 3.1.3.SP1 (bundled with JBoss Tools), I can't open some process definition files with the graphical designer. I have the following stack trace :

      My process definition looks very simple yet. Here is the processdefinition.xml file :
      <?xml version="1.0" encoding="UTF-8"?>
      
      <process-definition xmlns="" name="automaticValidation">
      
      
       <start-state name="start">
       <transition to="automaticValidation"></transition>
       </start-state>
      
      
       <decision name="automaticValidation">
       <transition to="refuse" name="nok"></transition>
       <transition to="accept" name="ok">
       <condition expression="#{decisionHandler.evaluateELExpression('EL_DECISION')}"></condition>
       </transition>
       </decision>
      
       <node name="accept">
       <action expression="#{absenceRequestProcessAction.acceptRequest()}"></action>
       <transition to="end"></transition>
       </node>
      
       <node name="refuse">
       <action expression="#{absenceRequestProcessAction.refuseRequest()}"></action>
       <transition to="end"></transition>
       </node>
      
      
       <end-state name="end"></end-state>
      
      
      </process-definition>


      I work with Eclipse Europa 3.3.2 on Windows XP Pro.

      Anyone has an idea what happens ?
