+AD4- +ACo- I've tried to transform only the gmfmap file to gmfgen, no change.
+AD4- +ACo- Then i re-build the model and edit code from the genmodel and
+AD4- transformed the gmfmap file again to gmfgen. Again no change :-(
Well, then the reason is not in the .gmfgen model state..
I can suggest you to start from one of the working GMF examples and modify
it step by step to your diagram. As a result you'll probably found the reason
for this error.
