public void selectTreeNode(NodeSelectedEvent event)
{

utree = (UITree) event.getComponent();
rowKey=(TreeRowKey) utree.getRowKey();
}

[tamri]

public class testBean
{
private UITree utree;
private TreeRowKey roeKey;
public void selectTreeNode(NodeSelectedEvent event)
{

utree = (UITree) event.getComponent();
rowKey=(TreeRowKey)utree.getRowKey();
}
}
after some operation(go another page and then return on this page)
call method
public String expandNode()
{
utree.queueNodeExpand(rowKey);
return "success";
}

this bean is sessionscope, so then i return on the treepage and call expandNode method it doesn't work;
