flushOnExecute and batch execute

[Amad Fida]

I have my sql map defined as follows...
 <cacheModel id="roleCache" type="LRU" readOnly="false" serialize="true">
   <flushInterval hours="24"/>
   <flushOnExecute statement="insertRole"/>
   <flushOnExecute statement="updateRole"/>
   <flushOnExecute statement="deleteRole"/>
   <flushOnExecute statement="deleteAllRoles"/>
   <property name="size" value="200"/>
 </cacheModel>
 <insert id="insertRole">
   INSERT INTO ROLES
   (roleKey, roleName, roleDescription, roleComments, createUser, 
updateUser, createDate, updateDate)
   VALUES
   (#roleKey#, #roleName#, #roleDescription#, #roleComments#, 
#createUser#, #updateUser#, #createDate#, #updateDate#)
 </insert>

there are other statements as well but this will explain my problem. 
When I execute "insertRole" with a SqlMapExecutor.executeBatch(), my 
cache doesn't get flush. Is not suppose to do that or am I missing 
something.

Thanks
Amad
