When I ran StepChat on gnustep and I set to load the MainMenu.xib instead of
MainMenu.gorm, an expception is raised with this message on the termianl:
2013-11-29 13:08:25.720 StepChat[8164]Is not possible to load the model file
'MainMenu'2013-11-29 13:08:25.750 StepChat[8164]

NSInvalidArgumentException2013-11-29 13:08:25.750 StepChat[8164] Problem
posting notification: <NSException: 0x121cd40>
NAME:NSInternalInconsistencyException
REASON:/usr/GNUstep/Local/Library/Headers/GNUstepBase/GSIArray.h:549 Assertion
failed in GSIArrayItem GSIArrayItemAtIndex(GSIArray, unsigned int).
NSInvalidArgumentException INFO:(null)
Note: I implemented the .xib on OS X (10.7, 10.9)
I made a backtrack and I attach here;
as you can see the aClass is nil, however in the backtrack log I made, there
are also the commands I ran to debug and see what is the problem.
I don't remember if the netiquette want to attach the file and also post here
the file content; to be sure I post also the file content here, but please
notice me if I shouldn't do.
Cheers,
Alex (Slex)
