var editor = new Ext.ux.grid.RowEditor({saveText : '更新',cancelText : '取消',clicksToEdit : 2});var grid = new Ext.grid.GridPanel({id: 'grid',region: 'center',autoWidth: true,。。。plugins: [editor]        });              grid.addListener('rowclick', function(obj, rowIndex, columnIndex, e){var record = grid.getStore().getAt(rowIndex);              id = record.get('roleid');  }, this);       editor.on({scope : this,beforeedit : function (roweditor, rowIndex){var roleid = grid.getStore().getAt(rowIndex).get('roleid');if(roleid == 10){return false;}else{return true;}},afteredit : function(roweditor, changes, record, rowIndex) {Ext.Ajax.request({url: '${contextPath}/project/manage/edit/userAction.do?action=updateRole&'&userid=' + userid + '&roleid=' + roleid + '&t=' + Math.random(),success:function(response){if(response.responseText.trim()=="true"){                                                id = null;Ext.MessageBox.alert('提示',"修改成功！",function(){store.reload();});}else{        Ext.MessageBox.alert('提示',response.responseText);                                        store.reload();     }},             failure:function(){Ext.MessageBox.alert('提示',"系统有误！");}});}});

? ? 当双击角色列是会提示this.items is undefined

? ? 经查找问题处在beforeedit 中，RowEditer.js使用的版本是3.0.0，官方网站上说此版本存在此BUG。

?

? ? 使用3.4.0版本的替换此版本，问题解决。
