> Hello,
> I have found something that is a bit strange. For @ManyToOne association properties in an @Embeddable class the cascade PERSIST, SAVE-UPDATE option is not  working well (not sure for the other cascade types), if the entities associated with ManyToOne are transient. I have created a unit test to check it and I have it attached to this issue. It is a maven2 project, and needs Oracle to run it. If I save the associated entites, then everything works fine, also the data structure is created well.
