Description:
===========
TIBCO ActiveSpace activity Unlock failed in sub-process when Lock has been executed in the parent process.

Environment:
===========
TIBCO ActiveSpaces 2.x/TIBCO ActiveMatrix BusinessWorks(TM) Plug-in for ActiveSpaces 2.0.x
All Operating Systems


Symptoms:
=========
Unlock failed to execute in a sub-process.

Cause:
======
This is a configuration issue. Checkbox "Spawn" is not enabled on the sub-process acitivity (sub-process executed in a separate thread).

Resolution:
========
The TIBCO ActiveMatrix BusinessWorks(TM) Plug-in for ActiveSpaces supports THREAD lock scope which means only the lock owner (in one thread) has the ability to unlock. To be able to use the unlock activity in a sub-process activity, enable the checkbox "Spawn" (default setting, sub-process executed by one thread).
