bingo ! that's it. Hey, this is a *huge* improvement
for my application!
OK, this is the second thing that I don't want
AndroMDA to default for me, the first one being
setting not-null="true" all over the place.
For now, I'm hacking maven code like this:
<replace dir="target/classes"
token='not-null="true"'
value='not-null="false"'>
<include name="**/*.hbm.xml"/>
</replace>
...but it would of course be better to have an
AndroMDA tag of sort for this. I think, Chad, you told
me to jira this thing about the not-nulls before. Not
sure though. Do *you* remember?
Now, has this outer-join business already been
addressed in the past, or is it going to be a new
feature request?

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?

No...only composition associations are by eagerly
loaded...which sets
[CB] By "default" I meant to say.
that lazy flag to "false" by the way you can turn
off the composition
defining
eager loading:
http://team.andromda.org/docs/andromda-hibernate-cartridge/namespace.html
(look for compositionDefinesEagerLoading).
That way you can use the lazy loading tagged value
when you need to define
eager loading.

Subject: 1:1 associations
chad,
are 1:1 relations eagerly loaded by default with
hibernate? I can't get rid of those cascades of
outer
joins in hibernate generated queries. by
"cascades"
I
mean that not only the 1:1 associations are loaded
but
then all the 1:1 associations reachable from
there,
and so on recursively.
Is this by any means normal?
