Subject Re: 1.1 best practice question - bug?

Hi Tom,

Thanks for that example.  I changed my code to almost exactly what you
have below and, while I got my unit tests to pass, I did experience some
odd behaviour.  The example you gave only seems to work if I have a
jdbc-connection-descriptor declared in repository.xml with the same
alias as the PBKey.  If I ommit the jdbc-connection-descriptor or give
it a different name, I get the npe discussed in previous posts (pasted
below for convenience).  This is reproducable and was using the latest
from cvs.  Just thought I'd let you know in case it's a bug.  Let me
know if you need more information.
