NETTIERS

hi, i'm starting using nettiers and i have i basic (i think) issue.

i'm using de datarepository to get all the records of a table in the bd.
also, i'm using de deepload method for a field to make an inner join with
another table.
the problem is that i want to make the join sending some parameters to the
query.
i don't want to make to join with all the secundary table, but also some of
them.

is it possible?

thank you!
