Hi,
With ojb 1.0.3 is it possible to fetch a relationship of a relationship ?
For instance, i have a class Vehicule which has a relationship on class
Value named values (it s a 1 to N ajustement) and class Value has a
relationship with class Ajustement named ajusts.
I've succed in doing addPrefectedRelationShip("values") but not with
addPrefectedRelationShip("values.ajusts")
Any clues ?
Cordialement

Hi jakob,
i'm using OJB 1.0.3, is "now" before this version or after ?
As far as i know it seems that you can tell that relationship are
autoretreived or not (depending on the value of the attribute
autoretreive).
In my case i don't want autoretreive so it is positionned at false, but in
some case i use addprefetchedrelationship in order to retreive relation
with the object itself.
But if i can fetch object A which has relationship on object B, i'm not
able to fetch object B relations while only fetching A. For the moment i'm
obliged to parse object B and manualy getthe relationship (with the
getters).
