When you bind one or more table columns to an array controller, the table view automatically binds its own content binding to the array controller (presumably with some heuristic for choosing one out of several, if you happened to bind different columns different ways). It doesn't seem impossible that the table view honors cell formatter errors only when its content binding isn't used (i.e. pure data source for all columns). That would explain the earlier behavior. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
