Dwr can´t find exposed method in wrapped service

Hi,

I have a wrapper to a class and expose this wrapper class to dwr. The 
problem is that dwr  can´t find the exposed method. The config is like this:

g2kstore-conf.xml
--------------------

   <bean id="consultaDocLogic" 
class="es.g2k.g2kstore.domain.servicio.impl.ServicioConsultaDocImpl">
       <property name="consultaDocDao" ref="consultaDocDao"/>
       <property name="mailSender" ref="mailSender"/>
       <property name="mailData" ref="mailData"/>
       <property name="paginado" value="20"/>
   </bean>   
  
   <!-- Transactional proxy para los servicios de aplicaciones -->
   <bean id="consultaDocLogicProxy" 
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
       <property name="transactionManager" ref="transactionManager"/>
       <property name="target" ref="consultaDocLogic"/>
       <property name="transactionAttributes">
           <props>
               <prop key="get*">PROPAGATION_REQUIRED, readOnly</prop>
               <prop key="*">PROPAGATION_REQUIRED</prop>
           </props>
       </property>
   </bean>. 

   <bean id="dwrConsultaDocLogic" 
class="es.g2k.g2kstore.domain.servicio.impl.DwrServicioConsultaDocImpl">   
       <property name="consultaDocSrv" ref="consultaDocLogic"/>
   </bean>
  
   <bean id="dwrConsultaDocLogicProxy" 
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
       <property name="transactionManager" ref="transactionManager"/>
       <property name="target" ref="dwrConsultaDocLogic"/>
       <property name="transactionAttributes">
           <props>
               <prop key="get*">PROPAGATION_REQUIRED, readOnly</prop>
               <prop key="*">PROPAGATION_REQUIRED</prop>
           </props>
       </property>
   </bean>   

applicationContext.xml (Here we have a  bean, dwrConsultaDocSrvSecure, 
wrapping a trasactional services and  with interceptors
to verify  acegi authetication, why dwr can´t  find exposed method in 
it?, if i expose consultaDocSrv to dwr all work ok)
-----------------------

   <bean id="consultaDocSrv" 
class="es.g2k.g2kstore.domain.servicio.factory.FabricaServicio" 
factory-method="obtieneServicio">
       <constructor-arg value="consultaDocLogicProxy" />
   </bean>
  
   <bean id="dwrConsultaDocSrv" 
class="es.g2k.g2kstore.domain.servicio.factory.FabricaServicio" 
factory-method="obtieneServicio">
       <constructor-arg value="dwrConsultaDocLogicProxy" />
   </bean>   
  
   <bean id="dwrConsultaDocSrvSecure" 
class="org.springframework.aop.framework.ProxyFactoryBean">
       <property name="target" ref="dwrConsultaDocSrv"/>
       <property name="interceptorNames">
           <idref local="dwrSecurityInterceptor"/>
       </property>
   </bean>


Any hints?.
Thanks Danny
