Hi Folks,
After switching from 0.2.0 to isis trunk (0.3.1 snapshot) I run into
an NPE (See stacktrace below). I probably did something wrong or
forgot something, but I have no clue what. HELP! :-(
Everything seems to work until I hit the "Ok" button when trying to
create a new object.
BTW. I switched back to in-memory persistor (from sql). What is
required to get the JDO persistor running or to get the sql persistor
back?
Regards,
Minto
