Code Generation Error for Meta Model Element named Enumeration [message #1213648]

Hello,

I have a meta-model element called Enumeration. When generating code I get an error in the factory class. The code generator does not know which class to use for the Enumeration (The Java one or the Meta-model one). Is there a way to define this in the Ecore or generator model?

Ralph,

I'm not sure why it should get confused about java.util.Enumeration
(after all, it cal deal with UML2's model that has Class, and Package).
Perhaps you can provide a simple example?

And UML also has a metaclass named "Enumeration"!

Hi

In my experience EMF codegen is pretty good about sorting out imports
even for difficulties like Class and Enumeration. This is becuase it
uses the already generated output as input to an updating merge. However
the downside is that if you have bad old content you get equivalently
bad new content.

Sometimes it is important to manually eliminate compilation errors from
your old code before regenerating it. If EMF gets it wrong, manually
correct it and it will probably then regenerate correctly.

Regards
