Hi,
I am creating a grammar that i built up using identifiers of integers.
What i am looking for is a way to cross-reference to integers. The xtext supports ID, but i have not found anyway to cross-reference to an integer.
regards,
Anders

Hi,

if you can change your grammar to somwething like this

grammar org.xtext.example.mydsl1.MyDsl1 with org.eclipse.xtext.common.Terminals

import "http://www.eclipse.org/emf/2002/Ecore" as ecore

generate myDsl1 "http://www.xtext.org/example/mydsl1/MyDsl1"

Model:
	elements+=Element*
	refs+=Ref*
;

Element:
	"element" name=IntRef
;

Ref:
	"ref" ref=[Element|IntRef]
;

IntRef returns ecore::EString: INT;

it will work out of the box
