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. FailedObject: my.package.A-0

    org.apache.openjpa.persistence.ArgumentException: Encountered new object "com.psi.vida.platform.entity.pojo.Account-com.psi.vida.platform.entity.pojo.Account-1010960" in persistent field "com.psi.vida.platform.entity.pojo.Application.account" of managed object "com.psi.vida.platform.entity.pojo.Application-com.psi.vida.platform.entity.pojo.Application-1010440" during attach. However, this field does not allow cascade attach. You cannot attach a reference to a new object without cascading. FailedObject: com.psi.vida.platform.entity.pojo.Account@537935
