Hi again!
I've realised that I cannot use a different index name. If my *class *is
*A3User* my index name must be *A3User.id* it can't have a different name
as (A3UserIdx), beacuse the internal funcion uses the dot as a separator to
obtain the classname and then call de DB to get that class.
There are other ways to do this?
Thanks in advanced!
Gerard.
