Hi Smeier
I've tried out 3.2.7, and haven't seem the problem reoccur since then. So
while I can't say for sure whether or not it was fixed, it certainly seems that
way.

Any ideas anyone? Could I write an MBean that set some property somehow?

This is under JBoss 3.2.3.
We deploy our application to clients with various datasources. To date we've
kept the datasource-mapping for the CMP layer in

Alex,
The problem ended up being my own fault (of course), as it usually does :)
The problem was that we had created our MSSQLServer tables manually, as our
application is already deployed to multiple clients and we can't depend on the
container to re-create tables from scratch every time.
Our
Update: I tried running the application on JBoss 3.2.6, but the same problem
persists.
Any ideas?

Hello
For the purpose of this example, assume I have two entities, X and Y, where Y
has a fk mapping to X such that:
Entity X:
public abstract Y getY();
public abstract void setY(Y y);
and
Entity Y:
public abstract java.util.Collection getXs();
public abstract void setXx(java.util.Collection x

Sure, just use the getTransactionInformation() method right before you obtain your
CMR collection to determine whether or not you are in a transaction.

If you are going to need to be able to access these values through CMP, you MUST
change your code. Unless there's something I'm missing here, all you will need to do
will be to just add another CMP field to your entity bean and then set your long value

Try putting some transactional debugging in your code, especially in the

If you need to temporarily modify an entity outside of the context of a current

Of course, make sure your existing transaction would not have already enrolled the
