That suggests you've forgotten to set the NSArrayController into "entity" mode, which is necessary for a Core Data property, which is modeled as a set rather than an array. In "class" mode, the array controller expects its content to be an array; in "entity" mode, it expects the content to be a set. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
