I think I know what causes my queries to "cascade"...
Needs checking, but I'd like to have your hearings
about this: it's all about the outer-join attribute in
the many-to-one, one-to-one, etc... mappings:
quoting from the hibernate documentation:
The outer-join attribute accepts three different
values:
* auto (default) Fetch the association using an
outerjoin if the associated class has no proxy
* true Always fetch the association using an
outerjoin
* false Never fetch the association using an
outerjoin
I guess if I set outer-join to "false", my problem
will automagically disappear... well, things are never
so simple (and for example, I don't have a clue about
the meaning of 'if the associated class has no
proxy')... let's try!
but, gosh, this may be a revelation, don't you think?
