Different filtered dataProviders for the same data?

Question

I have several lookup tables, some of which refer to or are relationships between others.

For instance, I have membership type included inventory which has Membership ID and Inventory Type ID and is the amount of each Inventory Type that one gets when one gets a specific type of membership.

When the user is reviewing an Inventory Type, I want them to see the amounts that go with each Membership Type; when the user is reviewing a Membership Type, I want them to see what inventory that membership would get.

Can I use a only one ArrayCollection for InvetoryType instances and only one ArrayCollection for MembershipType instances and somehow create filters to get different "views" of the data?

Each "view" would need its own cursor, sorting sequence, filter, etc.

Cheers

You can use a single Array instance with multiple ArrayCollection instances. If you're just displaying data, or sorting and filtering using the methods/properties provided by ArrayCollection (rather than editing the Array directly), it should have no effect on the underlying shared Array.
