Al Daher [http://community.jboss.org/people/baltajino] created the discussion "JBPM 3.1 Exception thrown on EndState" To view the discussion, visit: http://community.jboss.org/message/630832#630832 -------------------------------------------------------------- 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 My Process definition <?xml version="1.0" encoding="UTF-8"?> <process-definition   xmlns="urn:jbpm.org:jpdl-3.1"
