The following error message is shown when redefining the syntax of variable declarations from Xbase:

Cannot find compatible feature type in sealed EClass XVariableDeclaration from imported package http://www.eclipse.org/xtext/xbase/Xbase: The existing reference 'type' has an incompatible type 'null'. The expected type is 'JvmTypeReference'.

See forum : http://www.eclipse.org/forums/index.php/t/261672/

It happens when using the following grammar:


grammar org.xtext.example.mydsl2.MyDsl with org.eclipse.xtext.xbase.annotations.XbaseWithAnnotations

generate myDsl "http://www.xtext.org/example/mydsl2/MyDsl"

import "http://www.eclipse.org/xtext/xbase/Xbase"
import "http://www.eclipse.org/xtext/common/JavaVMTypes" as jvmTypes
import "http://www.eclipse.org/emf/2002/Ecore" as ecore

Model:
	greetings+=Greeting*;
	
Greeting:
	'Hello' name=ID '!';

JavaVariableDeclarator  returns XVariableDeclaration:
	{XVariableDeclaration} writeable?='final'? (type=JvmTypeReference name=ValidID) ('=' right=XExpression)? ';'
;


Reproducible: Always

Steps to Reproduce:
1. Do a fresh eclipse/xtext install 
2. Create a new Xtext project
3. Copy the very short grammar to the mydsl.xtext file.
