Hi,

i am running my first JBPM example and i am encountrin a thrown exception at the end of the process.
The flow from start State through the next Nodes is gone smoothly except when the token is at end State i get the following exception message
 org.jbpm.JbpmException: can't leave node 'EndState(endProjectManagementProcess)' without leaving transition
What i understand is that it's expecting a transition  a transition on End State Node. But what i know is that end state has no further transactions.
Exception is thrown in Node class cz Transition is null
