Hi
I am new to modeling, and recently started using GMF. After going through part 1 & 2 of the mindmap tutorial, i started a new project from scratch, but i ran into some problems. Basically, as far as i have gotten, i have 1 Eclass that i would like to generate for. When trying to generate a genmodel, i get these error messages of the type:
"Validation failed unexpectedly for", followed by the name of each of the elements in my mapping. The error messages in the log all says the same:

Does anyone have an idea of what could cause this?
Cheers!

I started over a bit, to simplify even more..
Right now, my ecore model consists of an Eclass called Class, which is contained in a DocumentRoot Eclass. The tool palette is generated straight forward i guess.. The gmfgraph contains a figure descriptor ClassFigure, which contains a Rectangle ClassFigure, which again contains a label ClassNameFigure. I also have a child access getFigureClassNameFigure, which points to the ClassNameFigure label. The node class has figure descriptor ClassFigure as a figure, and diagram label ClassFigure has the child access mentioned as accessor, and figure descriptor ClassFigure as figure.
In mappings, i have a top node reference with containment feature DocumentRoot .classRoot:Class. I then have a node mapping, with domain meta information element Class, diagram node Node Class, and tool creation tool Class. With this, i can generate a generator model (although when running i can't actually draw anything ). But, when i try to add a label mapping (feature label or label), i get error messages like before (slight difference from before in the casting though):

Edit: Started over again, and now it works.. gotta love gmf error messages though
