the hibernate 3 road map now states that it supports unidirectional one-to-many associations mapped to a not-null foreign key.
http://www.hibernate.org/200.html

The hibernate documentation talks about unidirectional one to many associations but it states:http://www.hibernate.org/hib_docs/v3/reference/en/html/associations.html#assoc-unidirectional-12m

why is it still not recommended? what are the issues in hibernate 3 with using a unidirectional one to many association?

ive read several posting that talked about this issue but non since hibernate 3 was released.
