radio button not working with panelgrid

<h:panelGroup style="width=20%;" >
<h:panelGrid columns="1" >
<h:selectOneRadio value="#{dao.radiotype}" valueChangeListener="#{dao.radioListener}"  on click="submit()" >
<f:selectItems value="#{dao.selectradio}"  />
</h:selectOneRadio>

<h:selectOneListbox size="5"  value="#{dao.selectlist}">
<f:selectItems value="#{dao.selectname}"/>
</h:selectOneListbox>
</h:panelGrid>
    </h:panelGroup>

<h:panelGroup>
<t:dataTable value="#{list.dao}"
     id="datatableid" 
     var="cd"
     rows="5" >
  <t:column >
<f:facet name="header">
<h:outputText value="#{msgs.id}"/>
</f:facet>
<h:outputText value="#{cd.id }"/>
  </t:column>
  <t:column>
<f:facet name="header">
<h:outputText value="#{msgs.delete}"/>
</f:facet>
<h:commandLink action="#{list.deleteAction}" value="delete">
<f:param id="cdId" name="cdId" value="#{cd.id }"/>
</h:commandLink> 
  </t:column>
  </t:dataTable>
      </h:panelGroup>

<h:panelGroup styleClass="rightpanel" >
<h:panelGrid columns="1">
<td><h:commandButton value="ADD" action="#{dao.generateid}"/></td>
    <td><h:outputText value="==================="/></td>

<h:panelGroup>
<td><h:outputText value="Id:  "/><h:outputText value="#{dao.id}"/></td>
        </h:panelGroup>

<h:panelGroup>
<td><h:outputText value="Title: "/>
    <h:inputText value="#{dao.title}"/></td>
</h:panelGroup>

</h:panelGrid>
      </h:panelGroup>
    
    </h:panelGrid>

<t:dataScroller rendered="true" for="datatableid"
pageCountVar="pageCount" pageIndexVar="pageIndex"
paginator="true" paginatorMaxPages="20"/>

</h:form>
</body>
</f:view>
</html>

here either the radio button group works fine or the rest of the command links and buttons work fine....
not both....
if the radio button group is cut then the rest of the command links triggers the action handlers but if the radiobutton is present then none of the action is triggered.....
if the menulist rendering is made static then the rest of the code works fine....but if it is dynamic then the command buttons and links in rest of the code does not work....

typically illogical problem....please help...

From your description I understand that the SelectOneRadio is creating the problem. I am guessing to be a prob with the converter... try using appropriate converter for selectOneRadio...

You can use JSF converter
<f:converter converterId="javax.faces.Long"/>
<f:converter converterId="javax.faces.Character"/>

Hope this helps
