Upgrade to 5.16 with error on workflows : the target isn't defined in the same scope as the source

[mapor]

Hello,

I have upgrade to version 5.16 and got this error on my workflow.

The error comes on flow that link a boundary event attached in a sub process to a service task in the subprocess.
I need the variable hold by the sub process.

The workflow is designed using the bpmn designer of eclipse.

Sample of XML generated by eclipse:

     <subProcess id="userValidation" name="User Validation">
         [….]
    </subProcess>
    <boundaryEvent id="reminderTimer" name="Reminder Timer" attachedToRef="userValidation" cancelActivity="false">
      <timerEventDefinition>
        <timeCycle>R/P7D</timeCycle>
      </timerEventDefinition>
    </boundaryEvent>
 <sequenceFlow id="flow27" sourceRef="reminderTimer" targetRef="servicetask1"></sequenceFlow>
      <serviceTask id="servicetask1" name="Send Reminder Task" activiti:async="true" activiti:exclusive="false" activiti:expression="#{mailingDelegate.sendValidationMail(execution, validationMailId, user)}"></serviceTask>
‍‍‍‍‍‍‍‍‍‍‍‍

I guessed that the flows have to be in the sub process tag to be validated but when i do that i got a NPE from FlowNodeHistoryParseHandler.

ActivityImpl activity = bpmnParse.getCurrentScope().findActivity(element.getId());
‍‍‍

This line return a null ActivityImpl

Is it possible to disable validation first since the workflow worked well in 5.15.1

So which variable are you trying to access? Why cant you have a boundary event that goes to a task outside of the subprocess?

My subprocess is a multiinstanceprocess, i'm trying to access to the variable that contains the current value of the list (user).

And i can't access to that variable without having the boudaries event link to a task inside that subprocess since that variable exist only in the subprocess.

I did a workaround by linking the boudaries event to only one task (since the others are service task).

But if i ever need to do that again within a more complex subprocess, i would like to know if i'll have to attach boudaries events to all the task of the subprocess or i can do it only by attach boudaries event to the subprocess and still access to the current value of the loop.

> i'm trying to access to the variable that contains the current value of the list (user).

Im not completely following, but what you always can do is attaching listeners that copy the local scoped variables to the global scope (and probably give them a unique name)

[mapor]

ok that's what i had already done as a work around.

Thanks
