status aspect on workflow

[evdgeest]

Hi,

I want to arrange that the workflow adds an aspect to the document every time the workflow changes between tasks, so when you view the details of that document you see his status in the workflow.

I added an aspect in the testmodel, and in the process definition I added a script in the transition part of the start-task. I keep on getting the errors below when starting the advanced workflow.

            bpm_package.addAspect ("test:Workflow_Status");

            executionContext.leaveNode();
          </script>
        </action>
    </transition>

I hope you can tell me what I am doing wrong!

Thanks in advance,

I hope someone knows the answer, because I am really looking forward to it.

Thanks,

I think it should look like this:

bpm_package.children[0].addAspect ("test:Workflow_Status", props);‍

Also, you might want to add line:

bpm_package.children[0].save()‍

See if it helps.

PS: not sure if executionContext.leaveNode(); applicable in transition. If transition is executing, leaveNode is probably already triggered…

Hi,

Can we add an aspect value in "review and approve" workflow and fetch its value? Can you please help me?
