Hi Guys, I am new to this, and so far very impressed with the whole thing, it is the best working, best graphical editor and generally best thought out architecture I have seen with regards to workflow engines.. I tried quite a few, but ended up with buggy imlpementations with very poor documentation.. anyhow, I ran into a problem today when trying to deploy a process definition from the graphical tool in eclipse containing any kind of mail functionality.. my exception from the logs is... for mail-node --------------- org.jbpm.jpdl.JpdlException: [[ERROR] line 47: cvc-complex-type.2.4.a: Invalid content was found starting with element 'mail-node'. One of '{"urn:jbpm.org:jpdl-3.1":swimlane, "urn:jbpm.org:jpdl-3.1":start-state, "urn:jbpm.org:jpdl-3.1":node, "urn:jbpm.org:jpdl-3.1":state, "urn:jbpm.org:jpdl-3.1":task-node, "urn:jbpm.org:jpdl-3.1":super-state, "urn:jbpm.org:jpdl-3.1":process-state, "urn:jbpm.org:jpdl-3.1":fork, "urn:jbpm.org:jpdl-3.1":join, "urn:jbpm.org:jpdl-3.1":decision, "urn:jbpm.org:jpdl-3.1":end-state, "urn:jbpm.org:jpdl-3.1":action, "urn:jbpm.org:jpdl-3.1":script, "urn:jbpm.org:jpdl-3.1":create-timer, "urn:jbpm.org:jpdl-3.1":cancel-timer, "urn:jbpm.org:jpdl-3.1":event, "urn:jbpm.org:jpdl-3.1":exception-handler, "urn:jbpm.org:jpdl-3.1":task}' is expected., and for mail action on leaving node ---------------------------------------- org.jbpm.jpdl.JpdlException: [[ERROR] line 35: cvc-complex-type.2.4.a: Invalid content was found starting with element 'mail'.
