incorrect fk-pointing-to-element-class value when using recursive collections and doclet

[Bradford Pielech <br...@alphatech.com>]

Hello:

	I have a class that acts like a standard DAG node, i.e. it has multiple 
parents and children that are each DAG nodes.  I am using the Xdoclet 
module to create the repository file and torque to create SQL and 
database.  I am representing the parent and children relationships using an 
indirection table.  My problem is this- the XDoclet module incorrectly 
generates the fk-pointing-to-element-class value.  Below is the generated 
mapping file and corresponding java source.  Notice that the
  fk-pointing-to-element-class element for the children collection should 
have a value of "child_id".
If I manually change this value, then the mapping and sql are correct, and 
my program behaves as I expect.

Mapping snippet:
----------------------------
<class-descriptor
     class="SimpleDAGNode"
     table="effect"
 >
     <field-descriptor
         name="ID"
         column="ebo_id"
         jdbc-type="VARCHAR"
         primarykey="true"
         length="35"
     >
     </field-descriptor>
     <collection-descriptor
         name="children"
         element-class-ref="SimpleDAGNode"
         indirection-table="parent_children_table"
         auto-retrieve="true"
         auto-update="true"
         auto-delete="true"
     >
         <fk-pointing-to-this-class column="parent_id"/>
         <fk-pointing-to-element-class column="parent_id"/>
     </collection-descriptor>

     <collection-descriptor
         name="parents"
         element-class-ref="SimpleDAGNode"
         indirection-table="parent_children_table"
         auto-retrieve="true"
         auto-update="true"
         auto-delete="true"
     >
         <fk-pointing-to-this-class column="child_id"/>
         <fk-pointing-to-element-class column="parent_id"/>
     </collection-descriptor>
</class-descriptor>
--------------------

Java source:
-----------------------------
public class SimpleDAGNode     {

   /**
    * @ojb.collection 
element-class-ref="com.alphatech.ebo.datamodels.SimpleDAGNode"
    *                 auto-retrieve="true"
    *                 auto-update="true"
    *                 auto-delete="true"
    *                 indirection-table="parent_children_table"
    *                 foreignkey="parent_id"
    */
   protected List children;

   /**
    * @ojb.field primarykey="true"
    * column="ebo_id"
    * jdbc-type="VARCHAR"
    * length="35"
    */
   protected String ID;

   /**
        * @ojb.collection 
element-class-ref="com.alphatech.ebo.datamodels.SimpleDAGNode"
    *                 auto-retrieve="true"
    *                 auto-update="true"
    *                 auto-delete="true"
    *                 indirection-table="parent_children_table"
    *                 foreignkey="child_id"
    */
   protected List parents;
------------------------------------

If I switch the order that parents and children are declared in the java 
file, the problem happens with parents, not children.  Thus, it appears 
something is amiss in the XDoclet.

Thank you very much for your assistance,
Brad
