    Execution Path of onMessage

      Hi,

       

      I was modelling a simple process that has a wait state through a pick-onMessage.

      After deploying the process, I created an instance which I could see that it was still running in the "Manage Instances" of the BPEL-console. However, selecting the instance and choosing to access the "Execution Path" threw me a NullPointerException.

       

      Note: the process seems ok because if I change this pick-onMessage to a simple receive (as the Quickstart_bpel_simple_correlation example), the process holds for the receive message and I can see the execution path. Plus, the exception comes from OnMessageImpl.

       

       

      Exception:
