thanks Andrus,
Well, I can't do this....
if o1 is in a dataContext, for example o1 is a child of O.
if I build o2 from nothing, o2 = new o2(), o2.set ... ect..
then if I do:
system.out.println(o1.getObjectid()), I will have all the values of o1
BUT
a println of o2.getObjectid() return null !
So to solve my problem, I did a simple fields comparison between the PK
attributes of o1 and o2 and it works ... but I thought there was another
way.
thanks
arnaud
