2 fields FK'd to the same table. Hibernate wont let me.

Using Hibernate 2.0.3, the following snippet of hbm.xml

Code:

        <many-to-one
            name="fromUser"
            class="bb.model.User"
            cascade="none"
            outer-join="auto"
            update="true"
            insert="true"
            column="UserId"
        />

        <many-to-one
            name="toUser"
            class="bb.model.User"
            cascade="none"
            outer-join="auto"
            update="true"
            insert="true"
            column="UserId"
        />

results in

"Repeated column in mapping for class bb.model.MessageHeader should be mapped with insert="false" update="false": UserId".

These aren't derived properties. Each instance of this object really is associated with two users: A sender and a receiver.

What have I done wrong here?

TIA.

Joe

Thank you.

And may I say, "Doh!"
