Do you want to end the workflow or current executing task ?

To end the current task and jump to next task you can use,
task->callback(0,"End the task"); in the perl script

This will close the current task and jump to the next task.

What you are using WFM or WFT? Also,state TS and OS version ?

The above assumes that

These are reasonable assumptions, but if any of the above is not accurate you may need to do something different (or fix the code to make the assumptions accurate).Also note - just doing a callback does not close the CGI window - you need to do that with a simple javascript directive, after the callback.

Yes ghoti is right, thanks for extra addition of points.

Thanks,
its got working
Is their any way to check this callback's second argument is next task.Means if Iam giving like
task->callback(0,"Success");
or
task->callback(0,"Fail"); from my cgi task(based on some conditions).

Next task in my workflow is a submit task,their I want check whether the CGITask was success.That is if the callback is "success" then I want to invoke submit task otherwise again it go back to cgi task.Is their any way to achive this?

It is based on the first argument not on the second argument. Second argument is comment for transition.

0- means Success and make transition to next task ---give transition name "Success".

1- means Failure and make transition to Failire task ---give transition name as "Failure".

For your problem, from CGI task give two transition i.e. first "Success" which points to the "Submit task", other is Failure which make transition to some dummy task and this dummy task again make transition to CGITask.

So in CGITask, make callback(0) only when your work is done and it will consider Success and automatically jump to next task i.e. Submit task with Success transition.

If your work is not done in the CGITask then make callback(1), so it will goto dummy task and then again will come to CGItask for completing it.

callback method first parameter is 0-based ordinal number of your external task successors.

So, if you have something like the following in your WF, then from the external task with these successors
$task->callback(0, "Success"); will transition your workflow to the 'success_task' and $task->callback(1, "Failure");
will transition to 'failure_task'

Thanks
I Understood what you said,.Iam very in workflow.
My workflow is like
Usertask1-->CGITask-->UserTask2
here if CGITask is success I want to transfer control to UserTask2 if it is fail I need to transfer control to UserTask1.Where I need to put dummy task.Iam very in workflow,So please find a solution for me.

When fails, instead of transfering control to the Usertask1, create dummy task, tranfer to dummy task, and again back to CGITask.

Dummy task dont do anything, just spacer for transfering to itself(CGITask).

This I said in case of WFM, I have not frequently used WFT, but it might be same for WFT also.

This makes no sense to me at all. How does this do what he said he wanted to do? What is the point of the dummytask? If the CGITask fails, simply transition to UserTask1. What do you need a dummytask for?

Ohhh...Soory...I thought, he does not want to do any activity from the user.
Soory, It's my mistake in not properly reading the thread....

Kannan1 ....u can just make transition simply back to Usertask1 from CGITask.

You don't need the Dummy task.....
