NSPredicate & Editor questions

Hey everyone,

I'm about to embark on understanding NSRule/PredicateEditors but before I get too deep into the code, I wanted to ask a couple questions.

I'm hoping to create an interface whereby the user can create an NSPredicate and then come back and edit it later. From what I've understood from the documentation and PredicateEditorSample, it seems that the appropriate way to do this would be to construct an NSCompoundPredicate from the editor. That way when the user goes to edit the predicate, I can easily break it up into its constituent parts by using the -subpredicates method of NSCompoundPredicate. Is that correct?

If that is correct, would I then have to determine with NSPredicateEditorRowTemplate I'd need to use by examining the subpredicate itself?

Or is there a simpler way to do this?

I appreciate any insight you have.

Thanks!

Dave DeLong
