Hello everybody,
I follow the GMF tutorial but using my own model (test.mdl) instead. Problem
occurs while I right click the test.genmodel and do generate model code,
nothing happens (also no error message). It should be generate code within 3
packages (test, test.impl, test.util) right? After then, I continue to
generate edit and got an error. The error shows in below. Does anybody know
what happen? Thanks a lot.

Meilin,
When code generation fails to generate, there typically is some
information about this in the error log. Have you looked at the error log?
In the Ecore editor, you can right click on any object and ask to
validate it but there are still many constraints not being checked,
i.e., https://bugs.eclipse.org/bugs/show_bug.cgi?id=75933 isn't done
yet. A common cause for failure is an EPackage without an nsURI or
name, or an EStructuralFeature without an eType.

Is your model valid? You can start the validation by opening your ecore
model and then select "Sample Ecore Editor"->Validate in the menu.
I had a NPE as well. The validation tool told me that I have forgot to set
some values in a Reference Element. After fixing the problem I was able to
generate the other models and the code without any error.

I found why I can't validate my ecore because the validation feature is
enable in single object
and can't be run on the top of ecore when opening the ecore editor.
Now, I know the problem was due to one of object missing eReference.
Thank you Ed Merks !
