If you want to get an exception and forbid main process to continue when it has an un-ended sub process instance, you could open an issue,  And we could achieve it in the next version. Thank you very much. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/548920#548920] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
