[Hibernate-issues] [Hibernate-JIRA] Commented: (ANN-389) @ManyToMany without mappedBy should be recognized as an error

[Emmanuel B. (JIRA) <no...@at...>]

    [ http://opensource.atlassian.com/projects/hibernate/browse/ANN-389?page=comments#action_23574 ] 

Emmanuel Bernard commented on ANN-389:
--------------------------------------

No, I mean that you can have 2 different associations one from A to B and one from B to A where the semantic of the association are completly different

let's say

User --owner--> Car
Car --hasBeenDrivenBy'--> User

So in this case I do have 2 different associations with a completly different semantic, none of them are bidirectional (but they could).

Sorry, my previous comment wasn't really clear

> Instead of letting the user know that something might get hosed, it creates two join tables, one for each direction.  I don't know when this would be the preferred behavior.
