Hey,
I am trying to create a metamodel in GEMS. I have eclipse Juno Release Build id: 20120614-1722 in ubuntu 12.04 64bit.
I create the empty meta modell and open it. When I click on "class" and into the view, I get an error in the error log:
java.lang.NullPointerException

Is GEMS compatible with eclipse Juno?
The GEMS project seems to be inactive for 3 years, is it still maintained?
Thanks!
Nathan
