<h:column id="column1">
<t:selectOneRadio id="interfaceId"
value="#{updateDeviceBean.deviceInterface.id}" forceId="true"
forceIdIndex="false">
<f:selectItem itemLabel=""
itemValue="#{vartableRow.id}" />
<a4j:support
action="#{updateDeviceBean.loadDeviceInterfaceDetails}" event="onclick"
reRender="mac" />
</t:selectOneRadio>
<h:message for="interfaceId" />
</h:column>
</a4j:region>
<h:column/>
