Betreff: Re: [Xdoclet-user] value-object and "almost" self-reference
Ooops,
it seems I didn't read the documentation enough...
The solution is explained
in "Exposing Generated Methods" of the "Using Value
Objects" document. Just
had to expose the missign interface.
Since
I've serached a lot for that little info, I thought it'd be nice to have
a
small paragraph in the documentation explaining how to do
"self-reference"
with entities and XDoclet. I could write it if some of you
are ready to
proof-read it. What do you think
?

So, I /think/ I'm OK here, no circular references. Now, for some reason
