[News.eclipse.technology.gmf] Re: Couple questions related with GMF

["ps" <paul.shi@xxxxxxxxx>]

Hi Martin,
Yes, I'm aware of that. The issue I had is when I generate the diagram code 
using GridLayout in RoundedRuleFigure, I always get a compilation error in 
RuleEditPart about this line:
org.eclipse.gmf.internal.codegen.draw2d.GridLayout myGenLayoutManager = new 
org.eclipse.gmf.internal.codegen.draw2d.GridLayout();

Basicly GridLayout can't be resolved.

So if you can use GridLayout, then that means the generation code works fine 
for you, that's something I don't understand.

Thanks for your response!

Paul
