Re: Stumped on "Attempt to insert null object...." when connecting to DB

lol, Chuck...you should get that cough looked at....although I did like what
came out. :)
I'm still missing something...hopefully you still have
some informational-phlegm left.

I specified com.webobjects.jdbcadaptor.SybasePlugIn in the model, but I
still see this in the log:

Mar 20 15:20:55 DataBuilder[2500] DEBUG NSLog  - Using JDBCPlugIn
'com.webobjects.jdbcadaptor.JDBCPlugIn' for ERXJDBCAdaptor@2610469

and I still get my error.
