Re: Help with NSTableView and NSPopUpButtonCell

[Fred Kiefer]

I fixed this in GNUstep gui SVN. The popup button cell didn't
synchronise it's title when the object value is set. I am not sure if
the fix is at the correct point. We could move it further down into the
selection handling of this class, but then the popup menu uses the same
methods and I am not sure, whether we want to synchronise there.

Hope this helps
