This is a braindead simple question, but I couldn't find a definitive reference.
Is it better to register an undo action inside or outside of a group? i.e., is this preferred: [someUndoManager beginUndoGrouping]; //do interesting things //end group first [someUndoManager endUndoGrouping]; //then register undo statement [someUndoManager registerUndoWithTarget:self @selector(undoSomehow:) object:magicalObject]; Or is this: [someUndoManager beginUndoGrouping]; //do interesting things //first register undo statement [someUndoManager registerUndoWithTarget:self @selector(undoSomehow:) object:magicalObject]; //then end group [someUndoManager endUndoGrouping]; I'd always done it the former way, closing my group first and then registering my undo target, and as far as I could tell it worked fine. But in trying to debug an issue, I reached a point where I started getting exceptions about registering my undo statement when no group had been begun. So on a whim, I swapped it to the second method, and that seems to have been the cure for what ailed me. But now I'm trying to confirm if that is a correct fix, or if it's just masking some other issue in my code (well, or both, I suppose). -Jim.... _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
