Hello, some days ago I wrote a little App to practice with NSCollectionView. I wrote it on OS X 10.6.8 XCode 3.2.2 and the relative IB; I ported the App on GNUstep and when I try to open the nib or the xib file with GORM, it is saying that:

"Problem Loading
Failed to load file. Exception: Index 0 is out of range 0 (in 'objectAtIndex:')

Last GORM update from the svn: Today.

I need this little App on GNUstep because I'll switch my little Calendar App to NSCollectionView as soon as I can and I'd like to have it on GNUstep, because I need specifically on GNUstep.

However, if I try to run the App without modify the nib file, it runs, but:

1) If I try to resize the window, it becomes totally black and the App is not usable. 2) If i click on the button "Add Student", it adds nothing. (It should add a view)

To implement the GUI, I used IB facilities for Cocoa bindings.

On OS X (10.6.8 and 10.10 too) the App behaves as expected.

The code is on github if you want to give a look. It's possible to try it with XCode (3.2.2, and probably it also works for XCode 6 because I have the same implementation on 10.10 and I did not remember differences on the implementation) or with GNUstep.
