I have an xcore model using bidirectional cross-references.

This is my grammar:
	greetings+=(Greeting| Test)*;
	'Hello' sample=[Test] 'age' age=INT '!';
	'Bye' sName=ID '!' 'see' 'you' date=ID';'

My xcore looks like this:
class Model {
	contains EObject[] greetings

class Greeting {
	refers Test sample opposite greet
	int age

class Test {
        refers Greeting greet opposite sample
	String sName
	String date

But I am getting this warning "The feature sample is bidirectional reference. This may cause problems in the linking process." How can I fix this warning? I cannot modify the Test grammar to include a reference to greeting.
