I cannot reproduce the issue. Could you please provide more details such as the mwe2 file and the exact location of the comment tokens?
Created attachment 200699 [details] Screenshot see attached picture for details about this bug
Created attachment 200700 [details] mwe2 file
btw: I just tried with a fresh Eclipse 3.7 + Xtext 2.0.0.v201106070531 and I can reproduce this bug... ~Serano
I tried to reproduce the bug with the attached file with different patterns but did not see the exception. What I tried: Move opening comment token (/*) a couple of line up / down (fast) Same for closing token Tried the same slowly (waiting for the reconciler to kick in) Tried the same with the complete comment section Tried the same with a couple of lines surrounding the opening / closing sequence. Please describe very detailled what you do to reproduce the bug (e.g. 5 lines up, 2 down, 5 up, 7 down, 1 down) and reopen the ticket if it succeeds with the latest builds.
Steps to reproduce this Bug on my Mac with Xtext 2.0 on Indigo 1 Workflow { 2 3 bean = StandaloneSetup { 4 scanClassPath = true 5 platformUri = "${runtimeProject}/.." 6 registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel" 7 registerGenModelFile = "platform:/resource/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel" 8 } 1) Open the org.eclipse.xtext.example.domainmodel example 2) Open the Workflow GenerateDomainmodelLanguage.mwe2 3) Add a comment (/* */) before line 3 'bean = StandaloneSetup {' 4) Remove the closing element of the comment (*/) 5) Add */ before the closing brackect } in line 8 6) Remove */ 7) Add */ after the closing bracket in line 8
