It is that the process definition is invalid or a bug of JBPM5.2" To view the discussion, visit: http://community.jboss.org/message/645877#645877 -------------------------------------------------------------- *Update* Hi, I found out what means "Event node 'event' [4] should specify an event type." It's because of it need to sepcify a org.jbpm.process.core.event.EventTypeFilter for each Event. I know how to add a EventTypeFilter for Event when coding in Process API directly. But now, I don't konw how to specify that through BPMN2 visual editor. Thanks.  -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/645877#645877] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
