[News.eclipse.technology.gmf] Modifying the generated code

[Arthur Molin <amoiln@xxxxxxxxxxx>]

Several of the threads on this board seem to recommend either changes or 
additions to the generated code. How many people using GMF are able to 
create a usable editor entirely from the models, versus how many are 
finding that they have to modify the generated code?

If you have modified the generated code, how do you go about it? Is it 
necessary to have a deep understanding of GEF to proceed?

My current problem involves having levels in my ECORE model that do not 
correspond to graphical items in the editor.  In response to my 
question, Artem Tikhomirov recommended:

I am afraid that I don't even know where to start looking for the 
child's creation command.
