I cannot understand why getProcessInstance() has to return Execution, it should return process instance by its meaning. And ProcessInstance is extends from Execution, it has all method declarations of Execution.  Return ProcessInstance is more clearly, and won't effect any Backward  compatibility. Do you have any idea about this? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/545077#545077] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
