Hi, 
      I have tried the fault node in drools flow file and it has worked fine in .rf. Whenever a faultnode is triggered it will search for the fault name and will be caught at the apropriate Exception Handlers. But When am implementing the same in .bpmn the fault node is triggered but the flow is not reaching Exception Handlers ie The flow will exit upon reaching the fault node. 

How can i resolve this problem?  

I will give the xml format of bpmn here
