Best Practices for Xtext

Cross References between 2 DSLs ¹

If you are using 2 different Xtext grammars and one depends from the other you must add referencedResource = Resource path to genfile to the mwe2 file in the language section. Then you need to add the dependency to the plugin.xml Then you must import it with import "nsuri" as shortMetaModelName and now you can reference it with shortMetaModelName::ClassName.

IMPORTANT: the importing DSL may show you a warning with the content "The imported package refers to elements in the package registry instead of using the instances from the workspace". DON'T USE the quick fix because it leads to an error in the generator!
