I'm starting to develop a BPEL designer extension. The
article about the Extensions is great, as well as the examples in the repository. My extension now can deal with new internal activities and primitive type attributes. However, I'm facing many problems to make relationships with other BPEL elements (for instance, my new element has a relationship with Variable). I could implement the serialization and the de-serialization of them (I think, I didn't test), however, the UI able to choose a variable is really hard to develop. I could see that this feature for Invoke (inputVariable and outputVariable), reply, onMessage, etc. is done by the class
InvokeVariableSection.I spent 2 days trying to understand how this class works, but unfortunately, I was not able.
Somebody knows another BPEL designer extension where I could see more examples of how to implement extensions for BPEL designer?
