Bug in autoredraw NSMatrix ?

[Jan Trembulak]

I thing that there is a bug in autoredraw NSMatrix (or NSCell).
When I set value of cell, the matrix (cell) isn't autoredrawed.
For example:
        When I set a value of cell with tag 'i':
                [[myMatrix cellWithTag: i] setIntValue: 0];
        then I must call: [myMatrix setNeedsDisplay: YES];

(In Openstep for Mach invocation of 'setNeedsDisplay' is unneccessary in
this case).
