Hi there,

I'm trying to generate GMF tool, graph and map model from my ecore model, however, i got this error : An internal error occurred during: "Generating GMF .gmfgraph, .gmftool and .gmfmap models".

And the error log look like this:

Any idea why?

Hi Chunbaixue,

Could you please try again with a fresh copy of the Epsilon distribution from [1] and let me know if the problem persists?

Cheers,
Dimitris

Hi,

Thank you for your reply!
Now the error is gone, i can generate everything from the fresh copy.
May I ask what the problem might be with my own version?

Hi Chunbaixue,

It's hard to tell but I suspect that your Eclipse installation contains multiple incompatible versions of Epsilon.

Cheers,
Dimitris
