>             Project: Hibernate Core
>          Issue Type: Bug
>          Components: core

> Comment from {{Cascade.cascadeProperty}}: 
> {code}
> // association defined on component
> // 		todo : this is currently unsupported because of the fact that
> //		we do not know the loaded state of this value properly
> //		and doing so would be very difficult given how components and
> //		entities are loaded (and how 'loaded state' is put into the
> //		EntityEntry).  Solutions here are to either:
> //			1) properly account for components as a 2-phase load construct
> //			2) just assume the association was just now orphaned and
> // 				issue the orphan delete.  This would require a special
> //				set of SQL statements though since we do not know the
> //				orphaned value, something a delete with a subquery to
> // 				match the owner.
