af:table, only the first row of the table is effect

Question

Hi experts,
I have an issue about using the <af:table, needs your help:
1.The default selected line is the first line of the table(This should be ok).
2.Only the first line can react to my manipulate, such as select one line and click delete button.
3.While choosing the other line-->click the command button, the page will be refreshed and the selected one will turned to the first line. (Now the selected row, will be the first row). And will do nothing ,and has no action with the command button.
I have an page OVS_Server.jspx, parts of it is :
<af:table value="#{backVS.serverList}"
var="row" rows="20"
emptyText="#{globalRes['ovs.site.noRows']}"
binding="#{backing_app_broker_OVS_Server.serverListTable}"
id="serverListTable" width="100%"
partialTriggers="poll1 commandButton_refresh commandButton_searchServer"
selectionListener="#{backing_app_broker_OVS_Server.onSelect}">
<f:facet name="selection">
<af:tableSelectOne text="#{globalRes['ovs.site.selectAnd']}" autoSubmit="true"
id="tableSelectOne" required="false">
<af:commandButton text="#{globalRes['ovs.site.server.poweroff']}"
id="commandButton_powerOff"
action="#{backing_app_broker_OVS_Server.powerOffAction}"
partialTriggers="tableSelectOne"
disabled="#{backing_app_broker_OVS_Server.unreachableServer}"
/>
<af:commandButton text="#{globalRes['ovs.site.edit']}"
id="commandButton_edit"
action="#{backing_app_broker_OVS_Server.editAction}"
/>
<af:commandButton text="#{globalRes['ovs.site.delete']}"
id="commandButton_delete"
action="#{backing_app_broker_OVS_Server.deleteAction}"
/>
</f:facet>
<af:column sortProperty="ip" sortable="true"
headerText="#{globalRes['ovs.site.serverHost2']}"
id="column_ip">
<af:commandLink text="#{row.ip}"
id="commandLink_ip"
shortDesc="#{globalRes['ovs.site.viewUpdateDetails']}"
action="#{backing_app_broker_OVS_Server.viewAction}"
immediate="true"/>
</af:column>
<af:column sortProperty="serverName" sortable="true"
headerText="#{globalRes['ovs.site.serverName']}"
id="column_serverName">
<af:outputText value="#{row.serverName}"/>
</af:column>
</af:table>
One JavaBean OVS_Server.java,and part of it is :
public class OVS_Server {
private CoreTable serverListTable;
private VirtualServer selectedServer;
public void onSelect(SelectionEvent selectionEvent) {
selectedServer = (VirtualServer)serverListTable.getSelectedRowData();
public String deleteAction(){
if (selectedServer!=null) {
deleteServerOper.execute();
return "deleteServer";
Would anyone show some lights on it?
Thank you very much.

Thank you for your reply!
But the example you mentioned also has the issue like one of the comments :
"Hi, on selecting the first row it displays the correct value, when navigating to another row still it displays the old value and not fetching the new selected row, actually I can see this on your sample screen shots... is there any way we can fix??"
Is there any resolution?
