Hi,

I have problems with my language; it's assumed that top level container name is equal to file name (resource) in which text of this model exist.

Model:
 class {Model} (name=ID)? {
    classElements+=ClassElement*
}

Some thing like this Model can be there but name is not mandatory. I come with extending DefaultEcoreElementFactory.set() to set default value to it... but I don't know how to get file/resource name as EObject?.eResource?.URI returns null .

Probably there is something that I can @Inject but what?

Thanks is advance.

Thanks
Krzysiek
