[rules-users] Alternate Flow Creation

In process flow i need to execute alternate path based on some external event. How can i do this ? For Ex:In a process (shown below) billing activity was implemented using work-item definition. Process goes to next node i.e. Do some task only after completing billing activity. I am calling completeWorkItem method after actually billing is done in the application, so that process goes to next node. http://drools-java-rules-engine.46999.n3.nabble.com/file/n1909549/flow.jpg But i have a requirement of once process is started (in the middle of billing activity) user may choose to cancel the process. So based on an external event i should do a compensating activity of billing and terminate the process. How do i trigger this alternate path? Thanks in advance for your help.
