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
