    Timer Boundary Event on ScriptTask ClassCastException raised at KnowledgeBase creation

      Hi,

       

      Some problems seems to occur when you set a Timer Boundary Event on a Script Task.

       

      When you try to create under eclipse a Knowledge Base with this kind of sample process (see attached file) you get the following exception :

       

      java.lang.ClassCastException: org.jbpm.workflow.core.node.ActionNode cannot be cast to org.jbpm.workflow.core.node.StateBasedNode
