BPMNError, ErrorBoundryEvent and spring

Hi,I have a "main diagram" that contains "call activity". "Subdiagrams" comunicates with buisness logic using the spring(in service task i use "Expression" to inject spring logic - "#{serviceCallActiviti.met5(execution)}"). In main diagram i use ErrorBoundryEvent to catch "BPMNError" from "subdiagra

Hi,

You'll have to rephrase your question a bit. I don't understand it now.

Best regards,

According the documentation BPMNError work with JavaDelegates or scripts. If i use JAVADelegate to run businessLogic everything is ok. The BPMNError is catch by "Boundary Error Event" and go to Service TASK(main diagram).

My question is: Is there any possibility to use BPMN Error in Expression ?

I look into code and i see how this Exception is being handled in Scipts:

ScriptTaskActivityBehavior line 57

catch (ActivitiException e) {
      noErrors = false;
      if (e.getCause() instanceof ScriptException
          && e.getCause().getCause() instanceof ScriptException
          && e.getCause().getCause().getCause() instanceof BpmnError) {
        ErrorPropagation.propagateError((BpmnError) e.getCause().getCause().getCause(), execution);
      } else {
        throw e;
      }

Mayby to handle BMPNError in Expression you can add the same code to the ServiceTaskExpressionActivityBehavior

Hi,

Yes I think it should be possible to also add this behavior to service tasks with expressions.
Can you raise a JIRA for this? And if you can also provide a patch that would be great of course.
