On deadlock.netbeans.org I was configuring a new project with two CVS modules,
'logger' and 'nbbuild'. I typed in

Module(s) [logger nbbuild______________v]

before noticing the down arrow. When I clicked that, it changed to

Modules(s) ---------------------

---------------------

OK... harmless, I thought, and saved the config.

When I next tried to build, logging failed:

--%<--
[workspace] $ cvs -Q -z0 -d /cvsup/nb_all co -D "Friday, April 20, 2007 6:48:53
PM UTC" logger nbbuild
$ computing changelog
cvs log: cannot open CVS/Entries for reading: No such file or directory
cvs log: nothing known about logger
nbbuild

ERROR: cvs exited with error code 1
Command line was [Executing 'cvs' with arguments:
'-d/cvsup/nb_all'
'log'
'-d'
'>=2007-04-19'
'logger

--%<--

Apparently Hudson thought the module was "logger\nnbbuild". I guess the textarea
control needs to be fixed to split on newlines as well as spaces before saving
to project configuration.
