How to implement conditional flows

created by Vincenzo Guastella in jBPM - View the full discussion

Hi all

 

I am learning jBPM and I am using the BPMN2 editor tentative release taken from:

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 ?

 

Thanks

 

Vincenzo
