[jbpm-users] [JBoss jBPM] - How can I suspend or resume a ProcessInstance in jBPM4?

Hi All: I have a big problem when suspending/resuming a ProcessInstance in jBPM4. A few days ago, I saw there are some feature for Suspending/Resume Execution in jBPM4. So I add this feature to the todolist of my project. But when I start work on this part, I find there is no method in api package to support these feature. First I think suspend/resume is similar with the end/delete operation in the ExecutionService.java, but there is no such method. So I go to the Execution.java, Fortunately, there are some code for the suspend: /** indicates that this execution is temporary suspended with the * {@link #suspend()} method. Human tasks of a suspended execution * shouldn't show up in people's task list and timers of suspended * executions shouldn't fire and the execution is locked. Make sure that comparisons are * done with .equals and not with '==' because if executions are * loaded from persistent storage, a new string is created instead * of the constants. */ String STATE_SUSPENDED = "suspended"; /** is this execution suspended ? */ boolean isSuspended(); But these are just a constants for the suspended state and a method for obtain the condition of the execution. I see there is some javadoc for {@link #suspend()}, it seems there may be a method named suspend in the Execution.java. But I can find any method like that. Finally I can only to use ExecutionImpl.java in pvm to complete the suspend() and resume() operation. I think there is totally wrong. /** * FIXME: It is wrong to use implement class. */ ((ExecutionImpl) pi).suspend(); /** * FIXME: It is wrong to use implement class. */ ((ExecutionImpl) pi).resume(); Anyone has better solution for this?
