I read some examples from the web on how to map N-to-N rellationship. But all the examples were about two tables (ie. Users and Events) and a third one (User_by_event).

I have to do something similar, but with trhee tables (ie. Users, Events and Foo), so I need a table like this: User_by_Event_by_Foo:

User_by_Event_by_Foo
*******************
* User_ID
* Event_ID
* Foo_ID

How should I use the many-to-many tag to map this table?

Thanks.
