Problem creating nested HashMaps using

[Utkarsh Ahuja]

Hi,
I am trying to create nested HashMaps something like

ParentHashMap {
    ...... some key value pairs
    ......
    childHashMap....some key value pairs
}

I am doing the following:

   <resultMap id="parentResultMap" class="java.util.HashMap">
       <result column="parent_column_1" property="parentColumn1" />
       <result column="parent_column_1" property="parentColumn2" />
       <result column="parent_column_1" property="parentColumn3" />
       <!-- customizations -->
       <result column="parent_column_1" property="children"
resultMap="childResultMap" select="loadChildren"/>
   </resultMap>

   <select id="loadParent" parameterClass="java.util.HashMap"
resultMap="parentResultMap">
       select
           parent_column_1,
           parent_column_2,
           parent_column_3
       from parent
   </select>

   <resultMap id="childResultMap" class="java.util.HashMap">
       <result column="child_column_1" property="childColumn1" />
       <result column="child_column_2" property="childColumn2" />
       <result column="child_column_3" property="childColumn3" />
       <result column="parent_column_1" property="parentColumn1" />
   </resultMap>

   <select id="loadChildren" resultMap="childResultMap">
       select
          child_column_1,
          child_column_2,
          child_column_3,
          parent_column_1
       from child
       where parent_column_1 = #parentColumn1:VARCHAR#
   </select>

Can iBatis instantiate and create a HashMap within another HashMap and use
the property element as the key for it ?
<result column="parent_column_1" property="children"
resultMap="childResultMap" select="loadChildren"/>

Thanks
