extendedDataTable dosen't work well

[lee64]

my code:

<h:form>
 <h:panelGrid columnClasses="top,top">
 <rich:extendedDataTable value="#{person.userList}" var="per" id="userTable"
 width="450px" height="450px" >

 <rich:column sortable="true" sortBy="per.userSno" filterBy="per.userSno" filterEvent="onkeyup" width="100">
 <f:facet name="header">
 <h:outputText value="Sno"/>
 </f:facet>
 <h:outputText value="#{per.userSno}"/>
 </rich:column>

 <rich:column sortable="true" sortBy="per.userName" filterBy="per.userName" filterEvent="onkeyup" width="100">
 <f:facet name="header">
 <h:outputText value="Name"/>
 </f:facet>
 <h:outputText value="#{per.userName}"/>
 </rich:column>

 <rich:column sortable="true" sortBy="per.classNo" filterBy="per.classNo" filterEvent="onkeyup" width="100">
 <f:facet name="header">
 <h:outputText value="Class"/>
 </f:facet>
 <h:outputText value="#{per.classNo}"/>
 </rich:column>

 <rich:column sortable="true" sortBy="per.userType" filterBy="per.userType" filterEvent="onkeyup" width="100">
 <f:facet name="header">
 <h:outputText value="Type"/>
 </f:facet>
 <h:outputText value="#{per.type}"/>
 </rich:column>
 </rich:extendedDataTable>
 </h:panelGrid>
 </h:form>

It's displayed just like a normal datatable.The input part like the first row in the online demo disappered.
What's the reason?Please help me.Thank you!

could you check the difference between our

 <rich:column sortable="true" sortBy="#{cap.name}" filterBy="#{cap.state}" filterEvent="onkeyup" width="170px">

and your

 <rich:column sortable="true" sortBy="per.userSno" filterBy="per.userSno" filterEvent="onkeyup" width="100">

code

That wasn't the reason,When type it here i made this mistake.
I redeployed the project.Now it renders a right view.
