I have a dynamic filter from a list box with 3 choices, which works fine.
I want to link this to secondary filter based on the 1st selection, but the 2nd list box does not update based on the selection from the 1st selection box.
I had thought I could put them in control containers, making the 2nd linked to the 1st, but sadly input tools in control containers are not supported 
Anyone have any ideas?
