I recently changed to v2.3 and now I'm getting the following error when executing the editor:
You are using a deprecated implementation of IjvmModelInferrer. Please change the type of the acceptor in your 'infer' method. It should be 'org.eclipse.xtext.xbase.jvmmodel.IJvmDeclaredTypeAcceptor'.This backward compatibility mode will be removed in the next release (2.3 June 2012).
My ModelInferrer is the generated one and I did not modify it at all. So I get
the "wrong" code generated.
