How to make "Assign to" dependent on "Assignment Group" in a record producer?

[Cory Miller1]

We want to limit the user list under "Assigned to" on a record producer based on the selected "Assignment Group"...

This will work for a List Collector as well, but you have to add 1 more step.  On the List Collector -> Type Specification tab, you have to add the following to the "Variable Attributes" field:

ref_qual_elements=assignment_group,no_filter

I added the ",no_filter" at the end as well because I don't like having the filters on List Collectors, but you can remove that if you would like.
