Call activity and boundary error event

[meditel]

Hi, i can't figure out why my process is not working as excepted 

I have a simple process that calls a call activity catching errors using a boundary event.

[attachment=0]ActivityProcess.jpg[/attachment]

The call activity process may throw an error if the msisdn != 0123456789 (PutOrderInDB.java)

public class PutOrderInDB implements JavaDelegate {

   @Override
   public void execute(DelegateExecution execution) throws Exception {
      String msisdn = (String) execution.getVariable("orderMsisdn");
      Long amount = (Long) execution.getVariable("orderAmount");
      String type = (String) execution.getVariable("orderType");
      System.out.println("msisdn from PutOrderInDB class : "+msisdn);
      System.out.println("amount from PutOrderInDB class : "+amount);
      System.out.println("type from PutOrderInDB class : "+type);
      if("0123456789".equalsIgnoreCase(msisdn)) {
         execution.setVariable("isPutInDB", true);
      }
      else {
         execution.setVariable("isPutInDB", false);
      }
   }
}

If i execute the process, i can't see in error in the tomcat logs, but the Activiti explorer remains looping and i can't move forward after that.

I have attached all the project files.
Any hints are welcome.

Is that a bug and shall i open a Jira ticket ?

Hi,

I deployed your process, but I can't figure out what your problem is.
If I use an amount of 90 and a msisdn of 0123456789 the process finishes as expected.
If I use an amount of 110 and a msisdn of 0123456789 I get another user task in my list.
All can be explained by the implementation.
So maybe you can explain in more detail what the problem is and how I can reproduce it.

Best regards,

Hi,
What if you use for example 50 as amount and 055668871 as msisdn. I that working for you ?

With kind regards,

Hi,

Then I also get the user task again, just as expected.
So what's the problem?

Hi,

Very strange!
For your information, i am using Activiti 5.7. I have deployed the same process as you and i used 50 as amount and 055668871 as msisdn and then Activiti explorer2 keeps looping and nothing happened 😕

Hi,

That's strange indeed. Can you add some additional logging to your process to see what's going on?

Hi,

I have found what was going wrong.
The called activity must make a reference to the error end event like this :

<error id="[b]myError[/b]" errorCode="error123" />
<process id ….
….
    <endEvent id="endevent2" name="ErrorEnd">
      <errorEventDefinition errorRef="[b]myError[/b]"></errorEventDefinition>
    </endEvent>

And the calling process must add the same error code to the boundary error event :

    <boundaryEvent id="boundaryerror1" name="" attachedToRef="callactivity1">
      <errorEventDefinition errorRef="[b]error123[/b]"></errorEventDefinition>
    </boundaryEvent>

But one more thing to mention here, is that Eclipse activiti plugin does not add automatically "<error id="myError" errorCode="error123" />" to the xxxx.bpmn20.xml generated code.

Hi,

This is not right. It's perfectly fine to have a errorRef="123" in the call activity boundary error event and an errorRef="123" in the error end event.
You don't need the error element to make this work. So the Designer only generates the errorRef="123" alternative.

I confirm.
