Migrating abstract entities can be problematic. For example, http://www.cocoabuilder.com/archive/cocoa/227970-migration-with-abstract-entities.html?q=Core+data+abstract+entity+migration+error#227970 > I tried creating an entity migration policy subclass but none of its methods > are called. Anyone have any ideas what the problem might be? Maybe you have not specified the migration policy in the Custom Policy: field of the relevant "Entity" form of the Mapping Model. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
