When setting an attribute in an object via the PUT_ATT script command, using GET_ATT would not properly set the correct value.
Investigation
For an example of this behavior:
Workflow has Queue "CLIENT_QUEUE", Script has queue "CHILD_QUEUE",
1) Workflow Script:
:PUT_ATT CHILD_QUEUE = GET_ATT(QUEUE)
==> Script runs in "CHILD_QUEUE"
2) Workflow Script:
:PUT_ATT CHILD_QUEUE = "CLIENT_QUEUE"
==> Script runs in "CLIENT_QUEUE"
The behavior in example 1 has been resolved.
