Extjs5 Uncaught TypeError：无法读取null的属性'metaData'

Question

未捕获的TypeError：无法读取属性＆＃39; metaData＆＃39;为null

我从Ext4移到了5，并且在尝试从treestore加载数据时发生了这个错误。有什么想法吗？

Answer 1

Ext.define(TreeSearchProxy, { extend: 'Ext.data.proxy.Ajax', alias: 'proxy.treesearchproxy', requires: [ TreeSearchResultsReader ], reader: 'treesearchreader', url : eaxies.util.Globals.ServletName, simpleSortMode : true, extraParams :{ ActionID: eaxies.util.Globals.ServletActions.RetrieveTreeSearchResults, query: null, dioikitikidiairesi: null, elementId: null, originalElementId: null, expandedNodeIds: null } });enter code here
