在actionscript Flex 3中动态创建OLAP DATAGRID

Question

我正在尝试在actionscript中构建OLAP Datagrid。有人有例子吗？

到目前为止，如果我使用mxml olapcube，那么当我尝试在actionscript中构建olapcube时，我的应用程序才能运行。

这是我的代码。

// SCRIPT

public var olapCube:OLAPCube = new OLAPCube();
private function loaded():void 
{
    //sends request.
    restRapport.url = "rapport_gridList.php?requete="+rapportRequete+"&champ1="+rapportChamp1+"&champ2="+rapportChamp2+"&champ3="+rapportChamp3+"&champ4="+rapportChamp4+"&champ5="+rapportChamp5+"&champ6="+rapportChamp6;
    restRapport.send();
    restRapport.addEventListener(ResultEvent.RESULT, olapFunct);
}

    private function olapFunct(evt:Event):void
    {           
        //OLAPCUBE.
        olapCube.name = 'cubeOLAP';
        olapCube.dataProvider = restRapport.lastResult.rapportlist.item;
        var dimensionArray:ArrayCollection =new ArrayCollection();

        //Dimensions.
        //Dimension 1
        var olapDimension1:OLAPDimension = new OLAPDimension();
        olapDimension1.name = "olapDimension1";
        var olapAttribute1:OLAPAttribute = new OLAPAttribute("champ1");
        olapAttribute1.name = rapportChamp1;
        var olapHierarchy1:OLAPHierarchy = new OLAPHierarchy();
        olapHierarchy1.hasAll = true;

        olapDimension1.hierarchies = new ArrayCollection([olapHierarchy1]);

        olapDimension1.attributes = new ArrayCollection([olapAttribute1]);

        dimensionArray.addItem(olapDimension1);

        //Dimension 2
