Could either be a regression or you're referring to stale model. The
latter could happen if you build your outline with references to the
EObjects of your model from outside a document transaction
(IXtextDocument.readOnly() / .modify()). The Xtext 1.0 API makes this
very easy that's one reason why we fully redesigned it in Xtext 2.0.
Could you file a bug with
- the version number you're using now
- a reproducible example?
