Hi ,
I was trying out an example of Referencing Elements of one DSL from another DSL . I followed this example from Christian.
http://christiandietrich.wordpress.com/2012/08/07/xtext-referencing-elements-of-one-dsl-from-another-dsl/
Here is my grammar
grammar org.xtext.example.definitions.Definitions with org.eclipse.xtext.common.Terminals
generate definitions "http://www.xtext.org/example/definitions/Definitions"
import "http://www.eclipse.org/emf/2002/Ecore"
Model:
definitions+=Definition*;
Definition:
'define' name=[EClass];
Referencing Grammar
grammar org.xtext.example.usages.Usages with org.eclipse.xtext.common.Terminals
generate usages "http://www.xtext.org/example/usages/Usages"
import "http://www.xtext.org/example/definitions/Definitions" as def
Model:
usages+=Usage*;
Usage:
'use' definition=[def::Definition];
Exception thrown while running
