提前感谢。我可以通过替换视图文件中的以下行来解决上述问题
Ext.define('rt.view.project.projectuser', {
extend: 'Ext.tree.Panel',
alias: 'widget.projectuser',
disabled: true,
border: false,
cls: 'projectuser',
autoScroll: true,
initComponent: function() {
Ext.apply(this, {
store: this.store,
items: {
title: 'User in project',
}
});
this.callParent(arguments);
},
});
store: this.store,
store: Ext.data.StoreManager.lookup('userinproject'),
谢谢。您有什么错误吗？看看这个：它应该会帮助你。你好，Abdel，我也检查了代码，但目前我没有收到任何错误。。我遇到了“me.store.getRootNode不是函数”的错误，我从该线程中解决了这个问题。目前我没有错误。不管我在做什么，实际上什么都没有改变。我还尝试使用extjs示例中给出的ajax代理。但它也装载空树。你还有别的想法吗？谢谢，但我没有看到您将存储重新分配到
initComponent
