I have a different problem but on the same topic.
The editor works fine but when i add the bpmn2 file to a KnowledgeBase i have this exception:
java.lang.IllegalArgumentException: Unknown gateway direction: Converging
at org.jbpm.bpmn2.xml.InclusiveGatewayHandler.createNode(InclusiveGatewayHandler.java:34)
at org.jbpm.bpmn2.xml.AbstractNodeHandler.start(AbstractNodeHandler.java:73)
at org.drools.xml.ExtensibleXmlParser.startElement(ExtensibleXmlParser.java:382)
....
I have this exception only with Inclusive Gateway, and only with Converging direction.
is it a bug or only I have this problem?
Cheers
