IIRC, this is expected behavior. Quirky, perhaps. What you probably want is to apply the predicate also as a filter predicate. OTOH this should cause the behavior you want > Is my predicate right?

No, I think it has to do with object caching, but don 't quote me on that ;-) > On a side note, does anyone know why I can't see the fetchPredicate > for an NSArrayController in the debugger? No such member seems to > exist. Why not? NSArrayController responds to -fetchPredicate. Shouldn't be any problem there. Just po [arraycontroller fetchPredicate]. Best, Keary Suska Esoteritech, Inc.
