Hi,
I am using the tutorial 3 example of ojb for
relationships n:m, but I am with a doubt. In the
example I have 2 forms, with and without intermediate
class. I made using the intermediate class (role) and
it functioned. Now I do not using the intermediate
class "role". Which object I have that to pass to the
method "store", person or project?????
Thanks,
Juliano Moraes
