Xdoclet, reference and modify-inherited

[Mickael LEFEVRE <Mi...@amdm.fr>]

Hello,

We use OJB 1.0.1 with one class per table.
To be simple, we have 3 classes : B extend A, and A have a reference to C.
The C id in A is anonymous.
A have the flag ' determine-extends="false" '

In B we could ignore the reference to C, but not the C id (which is
anonymous).
If we put :

 * // reference
 * @ojb.modify-inherited name="C"
 *        ignore="true"
 *
 * // foreignkey of the reference
 * @ojb.modify-inherited name="CId"
 *        ignore="true"

xdoclet-ojb simply reply :
<<The reference C in the class blabla.B uses the field CId as foreignkey
although this field is ignored in this class>>

If I delete :
 * @ojb.modify-inherited name="CId"
 *        ignore="true"
the ant task did well, but the field CId is present in the mapping of B.
That give bad SQL request on the database server, like if the field CId is
in the table associated to C.

We try to delete the anonymous CId field in the B mapping, and our test
succeed.
We could access the C reference from B. No bad join, or bad place field in
the SQL request.

Is it a bug, a feature, or something else ?

Michael

You've hit a bug. The constraint was checked for the reference even 
though it is ignored.
I fixed that in CVS (both stable and 1.1-dev). You can get the new 
module jar here:

http://cvs.apache.org/viewcvs.cgi/*checkout*/db-ojb/lib/xdoclet-ojb-module-1.2.1.jar
