*** Issue 126273 has been marked as a duplicate of this issue. ***

From issue #126273:
1. grid1. 
2. <CTRL+SPACE>
3. <SELECT setChoiceColumnVisible>
4. IDE inserted         grid1.setChoiceColumnVisible(rootPaneCheckingEnabled);
5. trying to change selected text "rootPaneCheckingEnabled"
6. exception

Unfortunately I am not able to reproduce it yet, even when I used the attached source and created some "dummy" closure
(used classes from these class).

I am going to integrate some fix in Flow tomorrow then I will let you know about the build containing the fix (the
problem is similar to the reported one, but probably it's not completely same).
Can you than try the new build?
Thanks,
Tomas

Hopefully fixed in: e43ae29fd08d
But I was not able to reproduce the issue, I've fixed one possible trace on which the inits may be assigned to null in
the  Flow, but I don't know if it was the only possible trace. Can you try a new build? I will attach a link when the
build will be done. If you will have still the problem please reopen this issue. I will send you a patched javac logging
the traces in the Flow.
Thanks,
Tomas

Here is the first build having the change: http://deadlock.netbeans.org/hudson/job/trunk/275/artifact/nbbuild/dist/zip/
Or you can use a night build which will come tonight or nay later build.
Thanks,
Tomas

Sorry. It is still in netbeans-hudson-trunk-295-java.zip.
Doing same thing: grid1., select "setChoiceColumnVisible", ide inserted
"setChoiceColumnVisible(rootPaneCheckingEnabled);", got exception.
After that i try to move cursor and got another exception:
java.lang.IllegalStateException: Cannot call getCompilationInfo() if current phase < JavaSource.Phase.PARSED. You must
call toPhase(Phase.PARSED) first.

The "java.lang.IllegalStateException: Cannot call getCompilationInfo() if current phase < JavaSource.Phase.PARSED. You
must call toPhase(Phase.PARSED) first" is consequence of the above NPE, will disappear when the NPE is fixed.

I've added some logging, for now high level logging.
The attribution phase of of javac has 3 phases before flow after parse (Enter - attributes class decl, MemberEnter -
attrtes features (methods, fields), Attr - attributes method bodies)
any of it may leave an empty subtree.
I will attach link to hudson when the build will be available.

Here is the link with the build:
http://deadlock.netbeans.org/hudson/job/trunk/306/artifact/nbbuild/dist/zip/
The IDE needs to be started with this additional flag to enable the logging:
-J-Dorg.netbeans.api.java.source.JavaSource.level=400

Just open the JNewFrame and generate the exception, in the messages.log there should be some additional information.
Thanks,
Tomas

Thanks for the logs, finally I was able to set up a reproduceable case.

Next try :-)
Fixed in: e80355b17b61

Seems this issue has appeared again. This appeared in nightly 200809140201.

The original reason is fixed, but there can be other reasons why the tree is not attributed.
Please attach the exception if possible file causing the exception.

The case with duplicated inner classes is fixed, but there can be other reasons why the tree is not attributed.
Please attach the generated exception dump file if possible.

Requested information was not provided, so I'm closing this issue for now. If you can still reproduce it

Restarted and cleared var/cache to try to get rid of this issue.  Attempted to rename an interface.

In case it's useful:  In another project (the file the compiler threw the exception on), there were a number of invalid implementations of the class I was trying to refactor - I'd changed it from an interface to an abstract class and manually copied and pasted a bunch of code into the parent class, changing its signatures.  The file in question also contained an import for a class in a non-existent package.
