[jboss-user] [jBPM] - How to implement conditional flows

Vincenzo Guastella [http://community.jboss.org/people/v.g] created the discussion "How to implement conditional flows" To view the discussion, visit: http://community.jboss.org/message/630725#630725 -------------------------------------------------------------- Hi all I am learning jBPM and I am using the BPMN2 editor tentative release taken from: http://download.eclipse.org/bpmn2-modeler/site http://download.eclipse.org/bpmn2-modeler/site I am trying to implement a conditional flow, so I added a Xor gateway and two outogoing sequence flows from upper and lower corners. I set the gateway as diverging, but I couldn't find a way to set the constraints. I checked the documentation and I understood that the constraints had to be added as conditions in the outgoing flows. But neither there I could find a way to set any condition. I thought that this part still was not implemented, so I edited manually the bpm file adding the child to bpmn2:sequenceFlow : <conditionExpression id="flow2_condition" body="eval(! $msgs.isRequestMsgEmpty() );"/> But I got the error message FeatureNotFoundException: Feature 'conditionExpression' not found. Is there something I am doing wrong or is it something still to be implemented ? In the second case where I can find some bpmn2 sample files ?
