[news.eclipse.modeling.gmf] Re: Custom Layout in Compartment

[Sven Krause <bugzilla@xxxxxxxxxxxxxxxxxxx>]

Hi,

I've had the same problem. After inspecting the gmf templates I've seen
a switch how to affect the generated result. A nested compartment figure
edit part is extending ListCompartmentEditPart where the inital main
compartment extends ShapeCompartmentEditPart. The key is the value for
ListLayout at the specific Gen Compartment within the created gmfgen
model. I have no glue what the initial value drives, but changing the
ListLayout to false remains recreation via gmfmap -> create generator model.

Hope this helps,

Sven
