that part of the code was not me, I think.
For the change notification I only asumed to get the *name* of a
renamed or removed element to be passed around (whether a class or a
method or whatever else), not the removed/renamed element itself (for
the reasons you mention). But the version in the image is not exactly
mine (whoever put it in there made some changes for better or for
worse), and this version does not seem to be from me. But ok...
I can fix this, I guess (I think that Nathanael was the maintainer
for the class builder, but I do not know whether he is still around
You need this urgently, I assume ?
PS: Can you reply personally to me as well ? I do not follow the
squeak list as often as I should :-( But I do fix things that get
included in the releases :-)
