How can I choose or make a proper diagram element? [message #1075992] Tue, 30 July 2013 13:21 Go to next message

I have got a given Ecore model what I have to use to make a GMF diagram editor. It was organized like that:

-main package
....-class A
....-class B
........
....-package A
........-class AA
........-class AB
.......
....-package B
........-class BA
........-class BB
........
I want to choose class A as a diagram element because it is the main class that represents the objects i want to draw with the GMF diagram editor. If I choose class A, I cant reach classes from package A, package B etc. which I also want to draw. How can I choose the proper diagram element or how can I do a better structure of classes to achieve what I want?

Hi,

is the meta-model linked to the other meta-models by references? If you could do so this could maybe help with you problem.

Dear Ralph,

no there are no references to other meta-models. I solved the problem, I had to disassembly the whole structure: I have only one package now with all of the classes. Unfortunately it is messy but GMF allowed only this workaround.

Thanks for help!

Hi,

did you have packages in packages in one meta-model? As far as I know it is discouraged to use packages in packages in EMF. Hence, you have improved the model Smile
