Re-Hi

My problem is almost at the same point than the other time. I don't
manage to get what I want from visual editor. The best I have is the
class name of the selected object.
I was wondering if there is any chance that visual editor defines an
extension point which permit modify the generated code. Because even
if I have an handle on the selected object (which will be already
marvellous ...), I don't know how to modifiy the right part of the
visual editor generated code ...
I tried to look at the source code because what I want to do is
exactly the same stuff that exists between the visual editor and the
property view but you guess it is not so easy to understand the
implementation (at least for me ...)

Please let me know if you have any ideas that might help me.

Many thanks,

Nicolas.
