>          Key: IBATIS-15
>          URL: http://nagoya.apache.org/jira/browse/IBATIS-15
>      Project: iBatis for Java
>         Type: Bug
>  Environment: iBatis 2.0.5.399
>     Reporter: Walter So
>     Assignee: Clinton Begin

> To duplicate this bug, you need two resultmaps:
>     <resultMap id="a" class="Parent">
>         <result property="id"        column="RELM_ID"       />
>         <result property="amount"    column="AMT" />
>         <result property="update"    column="UPDATE"       />
>  	</resultMap>
>     <resultMap id="b" class="Child" extends="a">
>         <result property="from"    column="FROM" />
>         <result property="to"      column="TO"   />
>     </resultMap>
> And two queries:
>     <select id="getAll" resultMap="a"  >
>         select ID, AMT, UPDATE
>         from TABLEA
>     </select>
>     <select id="getSome" parameterClass="string" resultMap="b" >
>         select ID, AMT, FROM, TO
>         from TABLEB
>         where ID like #value# 
>     </select>
> The problem is when get sql.queryForList("getSome", id) gets executed, iBatis doesn't throw an error, but returns a collection of uninitialized Child objects.  After scrutiny, I learned it was because the column "UPDATE" was omitted from the query.  Normally, iBatis will throw an Exception if not all the properties are mapped.  In this case, it does not complain when a resultMap is an extension of another.
> I was able to diagnose this problem by rewriting the "b" resultMap without "extends".
