Errpr inserting data in primary key(Key generated by JBOSS)

[sahumx]

I am not sure what is going wrong: I am using JBOSS 3.2.2+mysql
I create CMP managed bean Customer->account->contactinfo->address.

Primary key are generated by JBOSS as the bean is CMP and I do not mention a primary key field AddressEJB_upk
But whenever there is any operation, it fails complaining that
java.sql.SQLException: null, message from server: "Column 'AddressEJB_upk' cannot be null"
I am not sure what is happening...
Anybody has any idea...

How do you configure primary key generation? Have you specified entity-command?

I used entity-command=default.
I am not sure what to use here...
