 Post subject: Identifier altered from 402881e40f075781010f075... to null

I've created a test case with two very simple classes, and two database tables (six fields total). If all I'm doing is creating an object, adding an instance of a Set defined as a one-to-many element, and then saving it, how is it possible that I'd be getting an exception telling me that the id key of the many instance has been altered? This all occurring within a session, and the error is generated when the transaction is committed.

Any help will be appreciated.

session.save(user);
tx.commit();

Code:
<property name="userId" insert="false" update="false">
<column name="user_id" not-null="true"/>
</property>
<property name="roleName" column="role_name"/>
<many-to-one name="user" class="dbtest.DBUser" column="user_id"/>


Why do you have a userId property as well as a collection which both point to the same column? Try removing the property for userId

To answer your question, when I started putting this together, it seemed like a fairly straightforward process. Once I ran into trouble, I began looking at other examples to see if there was something I could identify that was incorrect. One such example had the fields mapped in this manner.

I removed the second reference to the user_id as per your suggestion, but I'm still getting the altered-id exception.

I should clarify - I removed the userId property, and left the collection element intact.

Check the setId method for 'Authority'.

Have you implemented it correctly?

Your mappings seems to be okay. There must be something wrong in your POJOs.

It's amazing how sometimes the most obvious things completely escape consideration. This was, indeed the problem (at least this time around). I noticed just as I was pasting the code for the POJO, that I was assigning the *existing* value of id to itself, rather than the value passed in the setter method. One of those "God, how stupid" moments. Thank you for your help.
