How can I use a subclass of java.util.Collection in Hibernate associations ?
For example, in a Customer class having an assocation with class Product via methods :

[code]public ProductCollection getProducts()

public void setProducts(ProductCollection products)
[/code]

I have to write an accessor class to convert a Collection coming from Hibernate into a ProductCollection and back. It works this way, but a lot of Hibernate's power with dirty checking and lazy retrieval is lost. Is there a chance Hibernate will support subclasses of java.util.* ? Or are there easier ways ?

In Hibernate3, use org.hibernate.usertype.UserCollectionType

Damn, I didn't knew that one, we rock :-)
