extjs combobox+treepanel节点重复问题

[mayixi]

var root = new Ext.tree.AsyncTreeNode({
id: "0",
leaf: false,
text: "",
expandable: true,
expanded: true
});

var loaderMeasureTree = new Ext.tree.TreeLoader({
clearOnLoad: true,
dataUrl: '',
animate: true,
method: 'POST',
preloadChildren: true,
baseAttrs: { uiProvider: Ext.tree.TriStateNodeUI, checked: false }
});

var measureItemTree = new Ext.tree.TreePanel({
animate: true,
root: root,
loader: loaderMeasureTree,
singleExpand: false,
iconCls: "icon-tree",
autoLoad: false,
rootVisible: false,
autoScroll: true,
allowDomMove: true,
height: 300,
frame: true,
collapsed: false,
collapseFirst: true,
border: false
});

看你写的SQL语句吧。

只要节点的id唯一就可以了，text值可以不管。

在你TreePanel中设置rootVisible为fasle，那么当树render出来的时候会自动加载一次。

你贴出来的代码是解决不了问题的。
还得贴出你另外加载树的代码
