jBPM5 Web Designer cannot open invalid BPMN2 process

Solution Unverified - Updated -

Issue

  • It has been observed that the jBPM5 Web Designer in BRM (i.e. Guvnor) cannot open invalid BPMN2 process. In order to reproduce the issue you can follow the below steps:
    • In BRM (i.e. Guvnor), create a new package, then create a new process under the package
    • Add start event, then task, then save -> OK
    • Add a parallel gateway, then save -> ERROR
    • Close the process, try to reopen it -> ERROR
    • As it does not allow you to open the process, you have no choice but to delete the package and create a new one

Can you please advise if it is a bug and if yes, then how to solve the problem?
