The application uses many MacOSX 10.3 features (I mean method and classes added in 10.3).
I had a runtime error because of such a missing accessor for a new defaultTabInterval property in NSMutableParagraphStyle.
So I decided to simply write a superclass and use the 'poseAs ' mechanism.
However, when I did so, I had this puzzling error message issued by the runtime (and followed by an exit(3)):
Assertion failed: impostor->instance_size == super_class->instance_size, file class.c, line 638
I'm kind of puzzled, couldn't you have new instance variable in a posing subclass?
That's the whole advantage compare to categories...
How could I work around that?
I need paragraph style information extensoively and absolutely, I can't simply remove the code using it....
