I have a workflow imbedded in a "invokeWorkflowActivity" in Workflow Foundation, VS2005.

My problem is that when I pass a variable as parameter to the nested workflow, I would like that workflow to manipulate the variable as pass it back to the calling (or parent) workflow. I passed an output variable to the inner workflow, it executed its operation on the output, but the return to the calling workflow shows that the variable is unchanged, obviously this is not a reference.

Do I use a "handleExternalEvent" in this case? How do I do this?

Thanks

Chris
