Hi Armin.
okay i didnīt know about 1.0rc5 isnīt
dealing with anonymous-keys.
so i do like suggested in 1:1-mapping.
but then in my Beans i have
int carId
Car car;
i do now:
setCar(Car c){
car = c;
carId = c.getId();
}
but i think this is redundant, isnīt ?
now i am very confused on dealing with OJB...
a short, and last question,
why doesnīt OJB1.0.rc5 not deal with anonymous-keys
i thought its a nice feature!
greetings ralf
