[News.eclipse.technology.gmf] Tools/Items icons assignment

[maciej <smartie@xxxxxx>]

Hi,

I have a problem with having different icons displayed for different 
children of an object.

My domain model looks like this:

 ________            _________
| Object | errors   | Message |
|        |--------->|         |
|        | warnings |         |
|        |--------->|         |
|________|          |_________|

The Object node has compartments for errors and warnings represented by 
labels.

The edit code generated by .genmodel file contains MessageItemProvider 
class with method getImage(...) always returning same image (generated 
Message.gif).
My Palette contains two Creation Tools, one for Object errors, and 
another for Object warnings. The icons I specify for them show in the 
palette but their diagram nodes still have the generated Message.gif icon.

Is there any way to bypass this (I want the icons chosen in .gmftool 
file to appear on a diagram as well) without subclassing Message to 
ErrorMessage and WarningMessage, so there would be two ItemProviders?
