Object references an unsaved transient instance
If you reference an entity in your statement, you have to make sure that it's already saved.

If this happens during saving an entity, you might want to cascade.

If this happens during a query, you might want to change your query
Foreign non-null entity is not saved
No solution
Persist multiple entities with same Id
Use saveOrUpdate for persisting entities.

In ManyToOne , ManyToMany ,OneToMany mappings you can use CascadeType.Merge to resolve this issue.
