Unable to find a value ...using operator "."

javax.servlet.jsp.el.ELException: Unable to find a value 
for "Name" in object of class "com.cabletech.plan.util.TreeNode" using operator "."

javaBean 中的变量首字母不能大写，要遵守java编码规范。

public class TreeNode {
	private String id;
	private String name;
	....
}

不能写成

public class TreeNode {
	private String ID;
	private String Name;
	....
}

这样之后就有可能找不到哦！
