org.apache.openjpa.persistence.ArgumentException: Attempt to assign id "0" to new instance "my.package.A-0" failed; there is already an object in the L1 cache with this id. You must delete this object (in a previous transaction or the current one) before reusing its id. This error can also occur when a horizontally or vertically mapped classes uses auto-increment application identity and does not use a hierarchy of application identity classes.

    org.apache.openjpa.persistence.ArgumentException: Attempt to assign id "domainopenjpa.Invoiceitem-null" to new instance "domainopenjpa.Invoiceitem@4fdf11" failed; 2. org.apache.openjpa.persistence.ArgumentException: cant-set-value ... What is the best way to persist Invoice into DB? Where I made ​​a mistake, and how to correct? Hi Rick, Exception stack looks like this: <openjpa-2.0.1-r422266:989424 fatal general error> org.apache.openjpa.persistence.PersistenceException: This operation failed for some instances. See the nested exceptions array for details.
