Re: SE 2.2 beta #2 code generation

Hi Philippe,

Yes, I had to do a substantial edit to fix update calls on expanded types to 
move to SE2.1, so I am aware of that as a possible cause, but I thought that 
all such changes to expanded update semantics had already happened for 2.1.

The code that is affected is my own adaptation of the Slyboots GUI classes 
from Sourceforge. All GUI widgets draw exposure events correctly, except for 
the tree widgets, so I know that the code path common to all widgets, which 
includes all the expanded class updates, is still functional.

I am currently at a loss as to what to look for, although I do know what code 
of mine must be affected.

Regards,

Howard
