Description tboerkel 2004-09-28 08:42:56 UTC 
After editing some lines during debugging, saving
the source and debug-fixing it, the editor combo
box (where all variables and methods are being
listed) is empty.
A maybe-related NFE appeared in messages.log.
Using NetBeans Dev 20040927 with JDK 1.4.2_05.
Attaching messages.log.

Comment 2 tboerkel 2004-09-28 09:09:59 UTC 
After a fresh start, changing a class during debugging and
debug-fixing it, it happened again. But this time without any
exception. The combo box is just empty.

Comment 4 Martin Matula 2004-09-29 14:59:45 UTC 
Tom, could you please look at the exception? It seems to come from javac.
Comment 5 _ tball 2004-10-01 20:35:19 UTC 
I cannot reproduce the empty combo-box problem with the latest build.
 Please reopen this bug if you are still having this problem.

However, the NumberFormatException in messages.log showed that my
scanner wasn't catching badly formatted integer literals.  I updated
the scanner to use the same logic that javac's parser does for
checking integer literals, so this exception won't be thrown any more.
Comment 6 tboerkel 2004-10-15 13:59:37 UTC 
I still have this problem with NB 20041012. If it happens, I also have
no code folding available in that source.

It just happened, after compiling this single source.

I think, this is related to issue #50146.
Comment 7 tboerkel 2004-10-15 14:11:09 UTC 
I can easily reproduce it now:

Compile the source: Combo box empty, no code folding.
Change/save the source: Everything OK again.

And so on...

Cause IMHO: Parser parses the newer file: .java or .class. 

Class files are in the same folder as the source files here.
Comment 8 tboerkel 2004-10-15 14:13:37 UTC 
Another thing: This causes problems with the debugger, too.
Breakpoints must be set again after compiling, changes, saving the
source. Otherwise it won't stop.
Comment 9 Martin Matula 2004-10-15 14:15:14 UTC 
Yes, this time it is very likely related to issue 50146.
Comment 10 Martin Matula 2004-10-15 15:53:28 UTC 
Hopefuly fixed by fixing issue 50146. I was not able to reproduce this
so I am not sure. So, please reopen if you get this even with the
build containing fix for 50146.
Comment 11 Jiri Prox 2005-07-12 12:17:24 UTC 
The editor combobox is no longer supported. Marking as verified.
