[news.eclipse.modeling.gmf] Re: Change Popup Strings and Icons in Mindma

["Joe Dente" <jdente@xxxxxxxxxxxxxxxxxx>]

Thanks for the response.
This worked well for replacing the icons as well as the labels in the popup 
menus.  I have one issue in that I needed to modify the elementTypes 
extension point in my diagram project.  If I added that extension in my own 
custom project, it would not override the behavior already dictated in the 
diagram's extension.  If I edit the diagram's extensions, then the changes I 
make will get overwritten the next time I generate diagram code.  Is there 
any way around this?
Thanks,
Joe.
