Could you please provide a grammar snippet that allows to reproduce the issue?
no..since the reason for this NPE was an (overlooked) error in my referenced test ecore file (a Reference without an EType set)...maybe we should close this bug as wontfix?..sorry for the noise. (In reply to comment #1) > Could you please provide a grammar snippet that allows to reproduce the issue?
We should fix this bug since incomplete ecore models should not cause an NPE in Xtext.
Preliminary scheduled for 2.0RC1
pushed to master
Closing all bugs that were set to RESOLVED before Neon.0
