Error boundary event on global scope

hi,

I am looking into catching BpmnError from any of the Java Service Tasks in the process.
Currently, I am able to catch error within the "subprocess" scope using the following process definition:

<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlnsmgdc="http://www.omg.org/spec/DD/20100524/DC" xmlnsmgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">

     <boundaryEvent id="boundaryerror1" attachedToRef="subProcess">
      <errorEventDefinition/>
   </boundaryEvent>
  </process>
</definitions>


How can I catch boundary event on the global scope (main process)?
     <boundaryEvent id="boundaryerror1" attachedToRef="???">
      <errorEventDefinition/>
   </boundaryEvent>


Thanks

Activiti assumes a boundry-event is always attached (attachedToRef) to an activity-instance. So using the process-id as value for "attachedToRef" won't work.

I'm afraid the only workaround is to contain all of your activities (except of start and end-events) in a subprocess…
