    Some problems controlling the mapping of CMR fields to table

      Hie all,

      I use a unidirectional relationship between 2 entity ejbs, I have a 1-M relationship, and would like to control the name of the relation attribute on the M side.
      I used the xdoclet tag @jboss.target-relation (which seems to provide this), but this does not work...

      On the 1 side the doclet and code is as follows :

      /**
 * Getter for CMR Relationship
 *
 * @ejb.interface-method view-type="local"
 * @ejb.relation name = "Prod-Prod2"
 * role-name = "Test"
 * target-ejb = "Products2"
 * target-role-name = "ProductsToProducts2"
 * target-multiple = "no"

 * @jboss.relation
 * related-pk-field = "pid"
 * fk-column = "pid"
 */
 public abstract Collection getProducts2();

 /**
 * Setter for CMR Relationship
 *
 * @ejb.interface-method view-type="local"
 */
 public abstract void setProducts2(java.util.Collection value);



      where pid is the pk of this entity.

      The ejb-jar.xml contains the following : 

      <relationships >
 <ejb-relation >
 <ejb-relation-name>Prod-Prod2</ejb-relation-name>

 <ejb-relationship-role >
 <ejb-relationship-role-name>Test</ejb-relationship-role-name>
 <multiplicity>One</multiplicity>
 <relationship-role-source >
 <ejb-name>Products</ejb-name>
 </relationship-role-source>
 <cmr-field >
 <cmr-field-name>products2</cmr-field-name>
 <cmr-field-type>java.util.Collection</cmr-field-type>
 </cmr-field>
 </ejb-relationship-role>

 <ejb-relationship-role >
 <ejb-relationship-role-name>ProductsToProducts2</ejb-relationship-role-name>
 <multiplicity>Many</multiplicity>
 <relationship-role-source >
 <ejb-name>Products2</ejb-name>
 </relationship-role-source>
 </ejb-relationship-role>

 </ejb-relation>


      and the jbosscmp-jdbc.xml contains : 
       <ejb-relation>
 <ejb-relation-name>Prod-Prod2</ejb-relation-name>

 <ejb-relationship-role>
 <ejb-relationship-role-name>Test</ejb-relationship-role-name>
 <key-fields/>

 </ejb-relationship-role>
 <ejb-relationship-role>
 <ejb-relationship-role-name>ProductsToProducts2</ejb-relationship-role-name>
 <key-fields>
 <key-field>
 <field-name>pid</field-name>
 <column-name>pid</column-name>
 </key-field>
 </key-fields>

 </ejb-relationship-role>
 </ejb-relation>


      Well, when the app gets deployed, the products2 table is created with a field named "products_products2" (while I was expecting "pid").

      I use jboss-4.0.0

      Where is the problem ?

      Thanks for help
