Hi Everybody i am facing an issue with hibernate. I have written two classes Company(Parent Object)and DBDCDeliveryAddress(child object) with the following mapping properties.

When i tried to save the parent (attaching the child data), i am getting
the following exception

net.sf.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing:
Could you please look into this and resolve this.

Thanks inAdvance.
