I looked a bit deeper and the problem seems to be, not so much with having a formatter attached to the field, but more essentially with returning no from the control:isValidObject: delegate method, when the text field's value is bound to an object controller. This causes the system to want to put up an alert and that appears to cause issues if the text field lives in a popover.
I created a minimal project exhibiting the issue, and will submit it to the bug reporter. -António On 22 Oct 2011, at 07:27, Antonio Nunes wrote: > On 21 Oct 2011, at 17:23, Nick Zitzmann wrote: > >>> 2011-10-21 11:49:49.520 AwesomeApp[35994:707] -[NSPopoverFrame >>> titlebarRect]: unrecognized selector sent to instance 0x1050e7a30 >> >> …often happens when an object was deallocated, and then some other object >> was allocated in its place, and then the original object was addressed after >> it was deallocated & something else took its place.
