Hi,

I sometimes receive the following error for one file(.mydsl). The other files still work normally. How can I solve this error?

Hi,
it looks like a problem in Xtext.

sometimes this error happens instead (when I do not reopen the file but just at typing):

I noticed that the outline refresher first throws a nullpointer exception like in this bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=381159#add_comment
It is the same bug because it also only happen if the file contains syntax errors...

The error I stated in post 1 occurs if I then reopen the file with the syntax errors

I think it has nothing to do with my grammar, could someone verify if he has the same issue?

I am currently observing the same problem. The stacktrace is exactly the same as above.

I have attached my grammar file. The error can for example be reproduced with a syntactically invalid input file containing the single line:

x=y)=

I have the same problem when opening files with grammar errors and the editor doesn't show up

Have you solved the problem?

No, the problem still is there. Maybe we should report a bug?

Yes, please file a bug with a reproducable test case attached and
describe the necessary steps to get the exception.

Hi

I've filed a bug trying to post the most reduced version of a grammar with the error: https://bugs.eclipse.org/bugs/show_bug.cgi?id=385636

Thanks

Sergio

I just recieved an email notification - this bug has been fixed. Thank you!

Quote:

AntLR changes the statemachine significant when small parts of the grammar are modified. We had a AntLRWorks debugging session and looked at the different szenarios. It turned out that in some cases nodes where reduced caused by the syntaxErrors and in some cases not. We decided to introduce a NPE guard in the DefaultLocationInFileProvider. So the editor will not crash for invalid models anymore. The attached grammar is used in a testcase to make sure that we will not have this problem again.

pushed to v2.3.1
