clone collection and save the realtion between the entries in the collection

[avihai marchiano]

Hey,

I suspect that there is no generic solution for this question , but i will try.

I have a collection (A) of entities (ejb3 ) "Foo" i need to clone this collection and to clean the data base id from the entities .

After clone i have a clone collection (B)

The issue is that i need to save in the DB the new clone collection and after i save i need know which entity in B is clone of which entity in A.

You can only do this if you have another unique property (or combination of properties) of the beans, such as the name. After all, there has to be a way to tell that two objects are still equal even though the ID has changed.

Yep, that what i thought. i try to see if someone else will find a creative idea , but i guess there isnt.

Thank you
