hi glenn,
thx for your reply.
foreign keys are well generated, objects creation works well.
my mapping is also almost like this one u show.. *but* my relation is
_inverted_ : since i have a B collection in C, ive declared my mappping like
this :
<class name="B>
<field name="b" type="B">
<sql name="b_id" />
</field>
</class>
<class name="C">
<field name="c" type="B" required="false" collection="vector">
<sql many-key="b_id"/>
</field>
</class>
is this wrong?
another question : ive read that castor doesnot support uni-directionnal
relationships, is this right? in fact my C object here represents a
CommandLine and my B object represents a Product, so i dont want C to be
navigable from B.. how can i achieve this? (cos if i dont declare a C
collection in B castor complains [need setter/getter methods])
