This is because the columns of the array collection are built dynamically off of the attributes of bound context node within Web Dynpro. The usage of string variables like col1, col2, etc are aliases for the actual column names. You bind the mapping within Web Dynpro of these column name alias variables to the actual attributes. At runtime they get filled with the context attribute names. You have to use the formatting becuase you starting to Flex to use the value in this variable as the actual column name. This gives you the freedom to change the names of the attributes on the WD side without having to change any coding on the Flex side. Give it a try.

And no there isn't really a forum dedicated to FlashIslands. We do have an RIA forum where purely Flex questions get asked sometimes. Although for topics related to the Islands framework, it is probably better to put them with the Web Dynpro Forum.

Hi,

I used a similar code in Flex to get array collection values from ABAP wd and display in my Flex datagrid, but it is not working. My datagrid is not displaying any values. Below is the code which I am using,

<?xml version="1.0" encoding="utf-8"?>

http://www.adobe.com/2006/mxml" layout="vertical" width="100%" height="100%" preinitialize="preInit()" initialize="initApp()">

<mx:Script>

<![CDATA[

import mx.collections.ArrayCollection;

import sap.FlashIsland;

[Bindable]public var ekkoDS:ArrayCollection;

[Bindable]public var EBELN:String;

[Bindable]public var BSART:String;

[Bindable]public var EKORG:String;

[Bindable]public var EKGRP:String;

[Bindable]public var ERNAM:String;

[Bindable]public var AEDAT:String;

[Bindable]public var BUKRS:String;

private function preInit():void{

ekkoDS = new ArrayCollection();

}

private function initApp():void{

FlashIsland.register(this);

}

<mx:DataGrid id="dg" dataProvider="">

<mx:columns>

<mx:DataGridColumn id="col1" dataField="" headerText="EBELN"/>

Can anyone let me know where I am going wrong?

Thanks!
