The org.eclipse.ocl.examples.xtext.tests plugin provides JUnit tests for the MDT/OCL Xtext editors. Running org.eclipse.ocl.examples.xtext.tests (standalone).launch on the Helios release, the testLoad_RoyalAndLoyal.ocl takes over 60 seconds when at most 1 would be reasonable. This slow performance was not always observable in all the M6/M7/RCx releases. Having changed the MDT/OCL grammar, the save of another file now takes forever seemingly, although debugging suggests some progress is being made.
bug 333976 proposes to solve this, since it gets rid of the backtracking algorithm.
This issue should be solved with the new serializer. Ed, could you have a look if you find time? The new serializer is enabled when you use the "SerialzierFragment" instead of the "ParseTreeConstructorFragment" in your workflow.

I thought this problem had been solved before Indigo; certainly my 'takes ages' problems went away and uncommenting a few save's in JUnit tests now makes no difference. So I'm not sure that I can confirm that the new serializer is good, but in the interests of moving on, I tried updating my 4.2.0.I20111007-1625 installation with tmf-xtext-Update-N201110171027. Total disaster; The 'Outline', 'Editor' and 'Miscellaneous' areas of the UI are blank; only the 'Explorer' area is shown. Attempting to show view Error Log gives an NPE on some Injection class. And just to make matters more fun Revert Configuration doesn't work either. Since 4.2M2 was fragile, and I've already got an improved Platform and UML2, I think I'll have to leave trying this till M3 when hopefully things will come together again.
(In reply to comment #5) > And just to make matters more fun Revert Configuration doesn't work either. But after killing it and Restarting, I have an updated installation after all. Before changing, editors regenerate and work as before. After changing I now get missing genmodel error messages. I'll investigate, but it looks as if you're not following the usedGenPackages closure.
Hi Moritz. Just found this on my 'action required' stack. I think we got this all sorted at/just after EclipCon NA. So resolved fixed??
