Navigate --> Go to Type...
start typing and exception occurs.

Impossible to use "Go to Type" action.
Comment 4 Vladimir Kvashin 2010-07-06 04:52:37 UTC 
Judging by the code, the only reason for such an exception can be that one of C/C++ modules did not load. This occurs when something is broken in your NetBeans userdir. 

Could you try with the clean userdir?

Sure, I'll add null check to the code shortly; but frankly, this won't make it work, just exception will gone.
Comment 5 Vladimir Kvashin 2010-07-06 04:55:35 UTC 
null check pushed to cnd-main:

Comment 6 _ hair 2010-07-06 05:26:52 UTC 
I'll test it out.

If the breakage is from the C/C++ module why does the Java "go to" stop working? Couldn't the breakage be enscapulated to C/C++ ?
Comment 7 Vladimir Kvashin 2010-07-06 07:57:40 UTC 
I agree, this shouldn't happen. And that's the fix I've just pushed to trunk fixes. I meant that for C/C++ it won't work. For Java it will - I checked.
Comment 8 Quality Engineering 2010-07-07 03:24:46 UTC 
Integrated into 'main-golden', will be available in build *201007070001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

looks good now using "Build 100714-5750efc684e1" (main's trunk last night).
