You don't get to this point, so it's not the problem you have now, but I assume your real code invokes [super initWithFrame:...]? > This is in the implementation of the class that controls the window the > browser is in: > > - (void)awakeFromNib { > [browser setMatrixClass:[SpecialMatrix class]]; > > [browser loadColumnZero]; > > NSMatrix *matrix = [storyLine matrixInColumn:0]; // <- return nil > matrix = [storyLine matrixInColumn:1]; // <- returns nil > } First step: Break in -awakeFromNib and verify that browser is not nil. Second step: Maybe an NSBrowser doesn't instantiate any matrices until you have responded to browser:numberOfRowsInColumn: with a non-zero value? — F _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
