Dynamic Sequential List of Approvers in the Human Task

Question

Hi all - I have this asynchronous BPEL process and want to dynamically assign a Sequential List of Approvers that are the result of an Invoke of a Database Adapter.
1. Added the OutputCollection of the Invoke as a parameter to the Human Task (element type).
2. Under Assignment and Routing Policy, chose Sequential List of Approvers, and By Expression, chose the value from the OutputCollection from the payload.
3. After deployment, the instance falls through to completion without errors, but without assigning a task to any approvers. I can see in the Invoke where it pulled the names I want to be assigned.
Any help or direction would be greatly appreciated.
Using JDeveloper 10.1.3.3

I tried to recreate the problem like listed above, but after I add the Outputcollection of the Invoke as a parameter, there is no schema info (not even task:task) when editing the Assignment and Routing Policy section. At any rate, there weren't errors to speak of - the instance completed with "The state of this instance is Completed".
In the meantime, I've used a while loop to loop through a sequence of approvers that are result of a query. I'll have to keep track of approvers and include them in each new payload I think.
