I've a problem to understand a feature of Nhibernate I've read the documentation, look at a couple of sample but never find what I wanted to realize.

I have a many to many association between two tables "Order" and "Product" which is a table "OrderLine" with just the two foreign keys.

I want the following behaviour:

If I delete an object "Order", it's always succed and delete also all OrderLines item linked to this Order. But it wil never delete a Product.

If I delete an object "Product", it can fail if some orderlines use this product.

Sorry but I think I don't understand really well the "inverse" and cascade attributes in the mapping :-(

Thx for your help.

inverse and cascade serve for different purposes. what you will want is to focus on cascade. if you want more specific help, post more details (mappings, classes etc)
