Some questions on Process Instance.

[jgreiner]

I just wanted to make sure I am doing some things using the best practice. I think I am doing some things that are not just 100% correct and work coincidentally

I have the process instance that I want to work with. What is the best method to get a Node so I can signal it? Also what is the best method to get a task so I can end it?

My Logic I am using on Node is....

 ProcessInstance pi = jbpmContext.getProcessInstance(pid);

 Token token = pi.findToken("MyNode1");
 token.signal("Pass"); // transition

My logic on a Task Node is...this is the one I think is not the best practice.

 ProcessInstance pi = jbpmContext.getProcessInstance(pid);

 Collection tis = pi.getTaskMgmtInstance().getTaskInstances();
 Iterator li = tis.iterator();
 while (li.hasNext())
 {
 TaskInstance ti = (TaskInstance)li.next();
 if (ti.getEnd() == null)
 {
 String ami = (String)ti.getVariable(ProcessVariables.ART_MASTER_ID);
 if (ami.equals(String.valueOf(artMasterId)))
 {
 ti.start(actorId);
 am = qm.retrieveArtMaster(artMasterId);
 }
 }
 }

Thanks

If you are in actions you can use the ExecutionContext : executionContext.getToken and executionContext.getTaskInstance...

Thanks for your response, unfortunately I am not in an Action.

The users has just finished the task on the web page (of my own design) and I am calling a ejb method that will then get the processinstance bia the process id and transition the task.

Looking at source code an running some tests I have found that way I am hitting the tasks is in fact incorrect. The code will give me all tasks even completed ones which might not be good.

I think what I would try to do is get the id of the taskInstance the user is doing and directly have it in your method...

In all cases I think you need something more to find the right taskInstance.

You know that is not a bad idea at all.....I can store the taskInstance ID on a Node-Enter event, then I can get the exact task instance every time.

That should work just peachy.....I will try to post the code here if it all works.

Thanks
