While porting a XText 1.0 project to 2.3, we have run in a strange error that we don't know how to interpret:
Element Rule1:{ModelB} should be in rule Rule2 but it is in Rule1

This is coming from function SerializerTester.assertSerializeWithjoutNodeModel() in AbstractXtextTests.getResourceAndExpect().

The corresponding grammar looks like:

Rule1 returns Rule0 :
    {ModelB} 'keyword' right=Rule2
   |{ModelC} 'keyword2' right=Rule2
   |Rule2 (  {ModelD.left=current) 'keyword3' right=Rule2
           | {ModelE.left=current) 'keyword4' right=Rule2)
;

Rule2 returns Rule0 :
  ...
;

The corresponding code parsed without error, and serialized correctly with node model. What could the error indicate?
