Subject: toplink essentials error messages need improvement
While I get the feeling that toplink error messages beat out
hibernate's, I think that messages like the following are pretty much
useless.
The first reaction I have when I see this is.. Why is toplink throwing
a nullPointerException... shouldn't it be in control? Also.. this
tells me nothing about what is going on.
These sorts of errors arise when attempting to access a Remote
entity's member collection with fetchtype Lazy & is no longer attached
to a persistance context. Can't toplink be a little smarter?
Thank you -
Matt
