Valang Validation in a portlet

[GrantGochnauer]

I am currently trying to use the valang validation beans from the spring modules project. I have been having problems when I add the Valang intercptor to my list of interceptors on the portletModeParameterHandlerMapping..

I have it currently defined as:

<bean id="valangMappingInterceptor" class="org.springmodules.validation.javascript.taglib.Val angRulesExportInterceptor"/>

<bean id="portletModeParameterHandlerMapping"
class="org.springframework.web.portlet.handler.PortletMod eParameterHandlerMapping">
<property name="order" value="10"/>
<property name="interceptors">
<list>
<ref bean="parameterMappingInterceptor"/>
<ref bean="valangMappingInterceptor"/>
</list>
</property>
<property name="portletModeParameterMap">
<map>
<entry key="view">
<map>
<entry key="user">
<ref bean="userViewController"/>
</entry>
<entry key="continueRegistration">
<ref bean="gatherUserInformation"/>
</entry>
</map>
</entry>
</map>
</property>
</bean>

and the stack trace I am seeing is:

Has anyone successfully used Valang validation inside a portlet? Perhaps there is something else I am doing wrong?
