BPMNError, ErrorBoundryEvent and spring

abol911

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 "subdiagram", but with spring it dosen't work(with JAVAdelegate everything is OK).

Mayby in ServiceTaskExpressionActivityBehavior class it can be done something like in ScriptTaskActivityBehavior in line 57

Hi,

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

Best regards,

If i run mianDiagram i get error:

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) {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; noErrors = false;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if (e.getCause() instanceof ScriptException<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; && e.getCause().getCause() instanceof ScriptException<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; && e.getCause().getCause().getCause() instanceof BpmnError) {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ErrorPropagation.propagateError((BpmnError) e.getCause().getCause().getCause(), execution);<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; } else {<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; throw e;<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }

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.
