Comment 4 Petr Hejl 2013-01-24 16:29:18 UTC 
Reporters can you provide a js file where this is reproducible?

This has been introduced in fix for issue #224215.
Comment 5 Petr Pisl 2013-01-28 13:05:59 UTC 
The file, where we can reproduce it, would be very helpful. I'm going to fix it without the reproducible case, but it would be better to have it. It is interesting how it is possible that the global object in our model is not a function.
Comment 6 Petr Pisl 2013-01-28 13:54:36 UTC 
Simple fix is committed in the web-main. 
http://hg.netbeans.org/web-main/rev/4d6743222872

Petr Hejl, could you please review the fix?

It's simple. The types are not resolved, when global object is not a DeclarationScope. 

Still it would be nice to have the reproducible test case.
Comment 7 Petr Hejl 2013-01-28 14:55:00 UTC 
The fix seems to be ok and safe.
Comment 8 Vladimir Riha 2013-01-28 15:45:18 UTC 
I tried some simple editing in more complex JS file, code completion, go to sources, refactoring etc. seems OK, no issue found + fix looks safe 

=> verified in trunk
