Could be - here's rdar://5293557 which is still open; it modifies the NSMutableString in place instead of going through the setter. It also plays merry hell with Undo - the validation prevents certain letters from being added to the string, but undo thinks they did get added so it tries to remove more characters than exist. 25-Jun-2007 04:05 PM Lee Ann Rucker: If I attach an NSFormatter to an NSTextField that has a binding set to continuously update values, the bound value gets updated the first time something is typed into the field, but not thereafter. I expected it to be updated every time, or not at all. >From Google and cocoa-dev searches, this seems to be a known problem or even >expected behaviour, but it is very annoying as the field in question requires >both validation and formatting (a Windows serial number which will fail if in >the wrong format). If there's a workaround for this please let me know. The attached program has a very simple formatter which demonstrates the problem - the top text field has a formatter, the bottom and otherwise identical one does not. 'FormatterIssues.zip' was successfully uploaded 24-Sep-2007 02:56 PM Lee Ann Rucker: Further investigation has revealed that the bound value *is* updated, but the accessor method only gets called once on the first change to the value. Even having accessInstanceVariablesDirectly return NO does not change this. _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
