Editor team, please evaluate bug. I do not see anything wrong in cnd side.

This exception now blocks Code Model tests. Important task for CND or Editor team.

It looks like BasicTextUI.editor is null. I'll attempt to fix it.
Btw what module's tests are failing? I've tried cnd.navigation and cnd.modelimpl and they pass fine. Is it random? If so please add RANDOM keyword.

No. It is not a OpenSource tests (out of NetBeans repository). C/C++ team uses some internal tool in order to check parser accuracy.

So please provide steps how can I reproduce the issue. Thanks.

Workaround is found. Special delay between open and close file is added.

Test scenario before fix:
for (file : AllFilesInProject) {
   openFileInEditor(file);
   isBadFile = validateFileInInternalAPI(file);
   if (isBadFile) {
       sleepInSeconds(3);
   }
   doSomeActions(file, isBadFile);
   closeFileInEditor(file);
}

Test scenario now:
for (file : AllFilesInProject) {
   openFileInEditor(file);
   isBadFile = validateFileInInternalAPI(file);
//   if (isBadFile) {
       sleepInSeconds(3);
//   }
   doSomeActions(file, isBadFile);
   closeFileInEditor(file);
}

Hello,

is this still P1 bug for the editor team??? Thanks,

David

Summary:
In order to analyze 622 files in IDE I miss about 826 seconds. Almost all time I am waiting while file will appear or disappear in editor. Additional time penalty (50 ms per file) will make my tests stable again.

Well, so the summary is also a complaint to shrink a per-file time or is it just a description of the current situation?
Anyway I plan to rewrite the Annotations class in post NB 7.0.1 time so I treat this as a requirement for the new class to not fail your tests.

Cnd team, could you please run your tests whether it will proceed fine now? Thanks.
