Hello,

I have type B inheriting from type A. Both types are not abstract in the meta-model. I defined and assigned figures and tools for both types. If I want to add B the subtype from the palette I get an exception while creation the view and nothing is displayed [1]. After closing and opening the file B is displayed with the figure of it's supertype A. Also the propertie's sheet displays A.

Hi,

not sure it is the same usecase. But I remember that sometimes you have to respect the "correct" order in gmfmap for the mapping for A and B. You should try to revert the order.

Aurelien,

you are so right. Changing the order in gmfmap, deleting the generator model and recreating it fixed the error. Thank you very much! Without you would have looked for this for years!

Thanks,

Ralph
