I have created an NSPopUpMenu that uses bindings to bind to a 'date'
attribute of a CoreData entity. This works well and I can select
dates and so forth. Unfortunately the dates in the pop up are of the
form "2005-09-27 00:00:00 -0400" which is a tad ugly. I want the
dates to be formatted like "Sunday, October 2, 2005".
So I created a quick NSValueTransformer that takes NSDates and
returns the correctly formatted string. I then set the value
transformer of the popup menu's "contentValues" binding to the name
of my newly created transformer. I also make sure +
[NSValueTransformer setValueTransformer:forName:] gets called before
the popup menu.
Unfortunately - the behaviour of the popup menu hasn't changed. It
doesn't seem to be using my value transformer at all - I've put
breakpoints/logs in the code and nothing.
Is there something special about popup menu transformers? Or it it
because this is bound to a Core Date object (I've never actually
needed to use value transformers with core date before)?
Thanks in advance.
Jon.
