[flexcoders] Filter An ArrayCollection By Multiple ArrayCollections (selectedItems)

[m_ollman]

I'm trying to think of the best way to approach this.

I have 3 main arrayCollections - store, store_category and 6 X 
categories (categories filtered into groupings).

A user would select several items from the cats AC's that would 
filter store_cats AC (the mappings). Then the stores with matches 
are filtered from the stores AC.

I have a filter function in place but can only figure out out to 
feed it one value - not an array of selected values from several 
DataGrids.

public function addMapping():void 
            {
                ac.addItem({dg1:selectedItem.text});
            }
            

Any thoughts throbbing Flex Brain?
