尝试在高级数据网格单元格中获取文本

Question

我有一个 AdvancedDataGrid，可以从 Web 服务加载数据。它只加载顶级内容，然后当您单击箭头时它会获取该数据。

我想做的就是找出某个单元格中是否有某些文本。我最初是这样做的：

public static function assertTextInAdg(params:Object):Boolean{
    // Gets the ADG
    trace('youre in the assertTextInAdg function');
    var grid:* = FPLocator.lookupDisplayObject(params);
    trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
    // Convert ADG to automation delegate to get an array of column names
    var newGrid:* = new AdvancedDataGridAutomationImpl(grid);
    trace('var newGrid:* = new AdvancedDataGridAutomationImpl(grid): ' + newGrid);
    var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData;
    trace('var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData: ' + datas);
    var columnId:Array = datas.columnNames as Array;
    trace('var columnId:Array = datas.columnNames as Array: ' + columnId);
    // Convert ADG data to an array of rows
    var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView;
    trace('var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView: ' + gridView);
    var gridData:HierarchicalData = gridView.source as HierarchicalData;
    trace('var gridData:HierarchicalData = gridView.source as HierarchicalData: ' + gridData);
    var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection;
    trace('var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection: ' + gridArrayColl);
    var gridArray:Array = gridArrayColl.source as Array;
    trace('var gridArray:Array = gridArrayColl.source as Array: ' + gridArray);
    var validator:String = params.validator;
    trace('var gridArray:Array = gridArrayColl.source as Array: ' + validator);

    for (var i:int = 0; i < gridArray.length; i++) {
        for (var j:int = 0; j < columnId.length; j++) {
            if (gridArray[i][columnId[j]] == validator) { return true; }
        }
    }

    throw new Error("Validator not found in ADG.");

}

如果数据是从代码中提供的，那么这是可行的，但现在我正在尝试使用从服务器提供的数据进行同样的操作，并且跟踪结果如下：

youre in the assertTextInAdg function
var grid:* = FPLocator.lookupDisplayObject(params):           companyDashboard.dashboardCanvas.dashboardGrid
var newGrid:* = new AdvancedDataGridAutomationImpl(grid): [object AdvancedDataGridAutomationImpl]
var datas:AdvancedDataGridTabularData = newGrid.automationTabularData as AdvancedDataGridTabularData: [object AdvancedDataGridTabularData]
var columnId:Array = datas.columnNames as Array: @objectName,@customObjectType,@owner,@value0,@value1,@icon1,@value2,@icon2,@value3,@icon3,@value4,@icon4,@value5,@value6,@icon6,empty
var gridView:HierarchicalCollectionView = grid.dataProvider as HierarchicalCollectionView: [object HierarchicalCollectionView]
var gridData:HierarchicalData = gridView.source as HierarchicalData: [object HierarchicalData]
var gridArrayColl:ArrayCollection = gridData.source as ArrayCollection: null

然后它失败了，因为它不能获取来源，我想。我对其他策略完全持开放态度，并且我已经在这个问题上困扰了 10 天。这看起来似乎是相对容易的。预先感谢您的任何意见。

**更新**

我一直在走一条略有不同的路线。我现在尝试使用光标迭代 HierarchicalCollectionView。这似乎有效。但是，当我获得节点时，我无法用它做任何有用的事情...我一直在寻找示例，但到目前为止它们都停在获得节点的地方。这意味着我知道这是一个愚蠢的问题。

 public static function assertTextInAdg(params:Object):Boolean{
    // Gets the ADG
    trace('youre in the assertTextInAdg function');
    var grid:* = FPLocator.lookupDisplayObject(params);
    trace('var grid:* = FPLocator.lookupDisplayObject(params): ' + grid);
    var adgData:* = grid.hierarchicalCollectionView;
    trace('var adgData:* = grid.hierarchicalCollectionView: ' + adgData);
    trace('AdgData.length() = ' + adgData.length);
    var cursor:* = adgData.createCursor();
    while(!cursor.afterLast) {
        var node:Object = cursor.current;
        cursor.moveNext();
 }

这是trace() 的输出：

youre in the assertTextInAdg function
var grid:* = FPLocator.lookupDisplayObject(params):     testApp.ApplicationSkin2._ApplicationSkin_Group1.contentGroup.Panel5.myADG
var adgData:* = grid.hierarchicalCollectionView: [object HierarchicalCollectionView]
AdgData.length() = 8

使用 selenium 和 FlexPilot 这就是我检查网格中文本的方式

selenium.flexAssertProperty("id=MyAppInFlex", "chain=id:userGrid/name:AdvancedListBaseContentHolder*/name:AdvancedListBaseContentHolder*, validator=text|Maria Marcano");

我有一些博客文章，其中包含有关 Selenium 和 FlexPilot 的信息
