It's a bit hard to tell, because there's too much getting tested at once here, but it looks like you have 2 possible problems: 1. Setting the frame on a layer that doesn't have a view yet doesn't do anything useful. This happens because the 'bind:...' invocation is going to cause the setter to be invoked initially, and in your non-working case, the view's layer hasn't been set yet. and/or 2. The setter is getting called with a value of 0. That would set the width and height of the layer to 1. There may a third thing going on too, but the other things are in the way. You need to set a breakpoint in the setter and examine to backtrace (call stack) to figure out when and why it's being called, I think. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
