Subject transactions have just suddenly stopped working
Date Thu, 16 Jan 2003 17:32:03 GMT
Hi,
I'm having a little trouble with my transactions.

I'm running Torque 3.0, Postgresql 7.2.1 (debian) and had transactions
working fine until a couple of days ago. They've suddenly just stopped
working though, and I was wandering if anyone had any idea why that
could be.

I do a

Connection torqueCon = Transaction.begin(UserAccountPeer.DATABASE_NAME);

which works, and the connection exists. However whenever I do something
like,

userAccount.save(torqueCon);

I get the following error,

java.lang.NullPointerException

I've had a look at the source and it doesn't seem to directly relate to
the fact that I am doing transactions. However as soon as I change the
line to,

userAcc.save();

it works. I kinda need transactions, so that is not a long term
solution. Does anyone know why torque could suddenly be borking so
unexpectedadly? As I said, exactly the same code was working fine until
very recently.

thx,
