我已经记录保存在数据库中我希望当我点击更新按钮时，它会从数据库中获取记录并默认选择并展开该记录，并显示所有其他记录但未选择但未展开，
这是我的模型代码：
public TreeNode getSelectedEmpMarketsForUpdate(int moID) {
ConnectionHandler conHandler = ConnectionHandler.getConnectionHandler();
Connection con = conHandler.getConnection();
Statement stmt = null;
ArrayList<MarketBean> list = new ArrayList<MarketBean>();
TreeNode root = new DefaultTreeNode(new BasicBean(1, "Root"), null);
root.setExpanded(true);
try {
ResultSet rs = null;
stmt = con.createStatement();
String selectQry = " select x.*,y.market_id as selected_id from (\n"
+ "select a.name as COUNTRY_NAME,a.id as COUNTRY_ID,b.name as ZONE_NAME, b.id as ZONE_ID, c.name as REGION_NAME, \n"
+ "C.ID as REGION_ID, d.name as CITY_NAME, D.ID AS CITY_ID, e.name as AREA_NAME, E.ID AS AREA_ID,f.name as MARKET_NAME, \n"
+ "F.ID AS MARKET_ID, concat(a.name,concat(b.name,concat(c.name,concat(d.name,concat(e.name,f.name))))) as completeName \n"

这里是xhtml：
<p:tree value="#{marketMappinBean.allMarketsRoot}"
selectionMode="checkbox"
selection="#{marketMappinBean.selectedNode}"
dynamic="true"
var="node" id="treeNode" animate="true" highlight="true" style="width: auto "
>
<p:treeNode >
<h:outputText value="#{node.name}" />
</p:treeNode>
</p:tree>
这是bean：
MarketMappingModel db = new MarketMappingModel();
selectedMarketsroot = db.getSelectedEmployeeMarketsTree(moID);
默认选择并展开不起作用，但所有记录都显示
