Description vtec 2004-11-02 11:43:40 UTC 
I have got this NPE when invoking "Fix Imports".
Afterwards the feature is unusable - have to
restart the IDE.

Comment 3 Martin Matula 2004-11-02 17:17:19 UTC 
Tomas, please evaluate.
Comment 4 Tomas Hurka 2004-11-03 13:27:32 UTC 
Please attach the source file, where you invoked "Fix Imports". Thanks.
Comment 5 vtec 2004-11-04 08:34:02 UTC 
Here is the file, it now looks different from the time when I have
encountered the NPE however "Fix Imports" still fails with the same
NPE whenever invoked witch is not the case with other source files in
the same project. The file is OK and compilable, so ho knows what is
going on?

Comment 7 Tomas Hurka 2004-11-04 14:56:32 UTC 
Thanks for the file. I can reproduce it.
Comment 8 Tomas Hurka 2004-11-04 15:28:19 UTC 
It seems to me like gjast problem. Somehow MULTI_PART_ID has second part (subtree with 
index 1) which is not IDENTIFIER. Please investigate.
Comment 9 _ tball 2004-11-10 03:55:06 UTC 
Fixed support for trees for the source pattern
"<multi-part-id>.super.<identifier>".  Tests had already verified that
"<multi-part-id>.super" and "super.<identifier>" worked.
Comment 10 Martin Matula 2004-11-10 19:47:59 UTC 
P3->P2 - this needs to be fixed in release40 branch
Comment 11 Martin Matula 2004-11-10 21:42:23 UTC 
I reviewed the diff and it seems to be OK. I also verified that this
issue is no longer reproducible.
Comment 12 Martin Matula 2004-11-11 09:21:44 UTC 
Fix merged to release40 on behalf of Tom.
