What is the use of forms tab on a sub-process configuration ?
It is not working as expected. the start form is started or displayed but the values do not get captured to the PV!
have anyone used the forms tab on a sub-process. how to configure the same.
Please do not suggest alternate ways.

You should only use the forms tab when an activity is attended, and really the only activity that makes sense as an attended task is a User Input Task. The forms tab itself is a bit of a legacy tab that existed when nodes were more limited. However, since there's a user input task now there's no need to use a form on any other node.
Can you describe why you want to make the sub-process an attended activity?
Basically, I need to use another application's process model (with a start form) without making any change to their code, utilizing maximum reusability. Hence I want that the sub-process start form to be executed when the sub-process is triggered. But, in actual when the sub-process is triggered it start its execution from the next node adjacent to the start node. Thus skipping the start form.
Even when I configure the start form in the sub-process although the start form is executed, the values are not returned back.
You don't want to use a start form for this. All you should need to do, is to put a User Input Task in your process flow before the Subprocess call, collect the data you want to pass into the subprocess, then call it. When called as a subprocess, the current start form in that process shouldn't have any effect on your process flow.
