Hi, I'm having some trouble with a number formatter that I can't make sense of:
I have 2 NSTextFields bound to 2 NSNumber properties in my model. Both text fields have NSNumberFormatters attached to them. One of the text fields will cause an alert when an attempt is made to clear the field, the other one accepts clearing/nil without problem. This is the desired behaviour, I want it to accept nil and just set the number in my model to nil.
The original XIB goes back to Xcode 3.2.x. The difference between the number formatters and the text fields is that one pair is old (created with Xcode 3.2.x on Leopard) and one pair is "fresh", created with Xcode 4.4 on Lion). However, their setup in IB is completely identical, down to the symbols configuration. The part that is visible in IB that is, there must be something hidden that is different. Bindings are set up identically as well, just the key paths are different.
Does anyone know what may be causing this? Do I really need to remove the old number formatter and re-attach a new one? I'd like to avoid that because if possible as I have a large number of those and the UI to set it up is painfully unhelpful.
In Leopard it was not possible to set up a NumberFormatter to accept nil at all. I actually subclassed it to make that work. With the 10.7 SDK is seems to accept nil values just fine. So maybe IB has a hidden flag somewhere to remember to use the old behavior?
Thanks for any pointers!
