Hello,

 

I have extract "UML.ecore" from the plugin and I add meta-classes in this file.Then I validate successufully the mapping file but when I'm creating generator model I find validation error like this:"Top level node 'Containment feature' must be available in the diagram 'Domain Element' or its super-class".

 

After that I have tried the same example with "UML.ecore" from the plugin directly and I haven't found this error. 

  
I need to know so if it's possible to do heavy extension to the UML.ecore????

And if it is possible, how can I correct this error?

 

Thanks a lot.
