No, it's a simple 'to many' property in my own model, not using Core Data. If it's trivial I can't find the solution - I have tried many things hinted at by the predicates guide. I am tired having worked a 14 hour day and counting, so perhaps I just need a rest to see the wood for the trees... I have a list of objects. Each object has a 'categories' property, which is another 'to many' property, i.e. a list. Each category has a simple 'name' property. I desire to match a string I enter to any of the categories.name strings in the list using equals, begins with, ends with, contains. I'm setting up the predicate editor in IB, but I can't see any way to use the aggregating predicate syntax anywhere there and when I attempt it I get a runtime error (e.g. no value for key 'ANY categories'). Perhaps it's a limitation of IB that more complex predicate editor row templates are not available? --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
