Description Ingo Meyer

Build Identifier: 

Somewhere very deep from the HighlightingHelper, i get the following stacktrace millions of times. I have to kill eclipse then...
I cutted something out which I think is unimportant, it is one of the longest stacktrace I ever get.

2011-12-14 16:52:50,270 ERROR [                    main] org.eclipse.xtext.linking.lazy.LazyLinkingResource: resolution of uriFragment 'xtextLink_::0.0.10.10.8.8.5.3.2::1::/0' failed.

Comment 1 Ingo Meyer

BTW, The error is coming when I move model code from one dsl editor to another.
After restarting Eclipse, doing the movement in text editors, restart again and open in dsl editor again, it works.

I don't want to spam here, but before you ask for the complete stacktrace, here it is:

Comment 2 Holger Schill

Could you please provide an example. In using the DomainModel or something. Until now I can't reproduce that.

Comment 3 Sven Efftinge

2012-01-05 04:41:34 EST

I've added a guard

Comment 4 Ingo Meyer

2012-01-05 04:50:51 EST

I will check that with the next release.
It is a very hard problem and I think that in rare cases I even get that in the Xtend editors after moving code between files.
