[news.eclipse.modeling.gmf] Parameterized creation tool?

[Andreas Mayer <an.ma@xxxxxx>]

Hello,

I have a model element (let's say Rectangle), which can be parameterized 
via an enum feature (let's say color : enum { RED, GREEN, YELLOW }). I 
can already create new rectangles via the palette and change the color 
feature in the properties tab. However, I would like to have additional 
creation tools in the palette, which directly create a red or green 
rectangle.

I've already searched the newsgroup for a solution and found [1]. As far 
as I can see, for each of the colors I would have to define an 
additional top level node in my gmfmodel, which includes a type model 
facet with an appropriate feature initializer. That's a lot of 
unnecessary duplication in the specification and the generated code.

Is there a more elegant way to achieve this?
