可以设置tree的adviseNodeOpened 和 adviseNodeSelected属性。

TRUE, a particular treeNode is expanded; java.lang.Boolean.FALSE, a particular treeNode is collapsed; null, a particular treeNode saves the current state
adviseNodeSelected false false javax.el.MethodExpression
(signature must match java.lang.Boolean adviseNodeSelected(org.richfaces.component.UITree))
