proxy : {

url : url //获取树节点的地址
}
}).load();
加载出来数据不显示
到底是TreeStore,出问题了还是？
//java类是这样写的，用的struts2
public class Tree {
private String id;
private String parentid;
private String rw_id;
private String rw_name;
private Boolean leaf;
private String rw_mustdata;
private String rw_sfwcname;
｝
很急，求解释
root : {
expanded : true
},
autoLoad : true
struts2返回的数据是什么

1、在页面没加载完成的时候已经创建了dom元素，将元素的宽高自动设置为了0。
2、你需要重写treePanel的load方法，将node.removeAll(true)更改为node.removeAll(false)。
