You could try setting the resultFormat property on the HTTPService tag to “array” when loading an XML file and see what type/format of an ArrayCollection object that returns. To get at the underlying Array object, you would just access the ArrayCollection object’s source property.

Apart from that, if you have a specific format you want, I’d suggest just writing your own code. Take the last result from the HTTPService tag, and loop over the ArrayCollection/XML results and construct your own custom array of objects in the specific format you need.

    <mx:Array id="arr">
        <mx:Object label="One" data="1" />
        <mx:Object label="Two" data="2" />
        <mx:Object label="Three" data="3" />
        <mx:Object label="Four" data="4" />
    </mx:Array>

but coming from an HTTPService from a .php file outputting XML

I totally understand how that works… but how can I do that when I’m returning XML from a DB?

What would my XML need to look like? Also, wouldn’t I have to put the XML into a XMLListCollection or XMLList?

My XML is currently returning something like this:

Peter
Andrew
….
and so on…..

Would I want to include the employees primary key in the XML?

Peter
20
Andrew
2

Basically, I understand the logic behind .selectedItem…. but am really confused how to work with the XML as supposed to hardcoding my Object Array.

Thanks!

I typically use <ComboBox>.selectedItem.<fieldName>, or, something like the following:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">

    <mx:Array id="arr">
        <mx:Object label="One" data="1" />
        <mx:Object label="Two" data="2" />
        <mx:Object label="Three" data="3" />
        <mx:Object label="Four" data="4" />
    </mx:Array>

    <mx:ComboBox id="comboBox" dataProvider="{arr}" />
    <mx:Label text="comboBox.selectedItem.label={comboBox.selectedItem.label}" />
    <mx:Label text="comboBox.selectedItem.data={comboBox.selectedItem.data}" />

</mx:Application>

Hope that helps,
Peter

I’m having an issue with understanding Flex’s HttpService calls. I’m looking to do something similar to an HTML Select with my form. I currently have 1 List box and 3 comboBox’s receiving XML data from my MySQL DB.

It is currently just populating the Label, however when I go to insert/update to the database I want to insert the Value (or Key) and not the label. How could I do this? I thought if I returned the result from the HTTPService as a result it would look more like an HTML Select, however I can’t think of how the combobox or list will know what to submit when a particular Label is selected… since they are usually a selectedItem or selectedIndex.

Sorry for my confusing text either way, any help would be greatly appreciated.

i read the other topic on your blog, we can use the function at the below to get the xml’s data on the data grid

private function resultHandler(event:ResultEvent):void	{
	xmlData = event.result.mynode.childnode.source as Array;
	xmlDataAC.source = xmlData;
}

but in this case the xml format is has different child node
One

image1.jpg
image2.jpg
image3.jpg

can i still use xmlData = event.result.album.name.source as Array; and
xmlData2 = event.result.album.image.source as Array; to get the data ?? i have tried that they were not work. do you have any suggestion to get the data from different node easily ?? because img0Text.text = resultObj.album.images.image[0]; is so hard to use when my xml has alot/ unknow lenght node.

I’m also encountering this issue… has anyone figured why this message occurs? Thanks!

Yeah, I’m seeing the same error (End of File). Let me know what you find out from Darron.

Peter

I’m getting the following error with Darron’s code (I emailed him as well).

Error #2030: End of file was encountered.

In ByteArray/readObject()

I’m returning an object from an ASP.Net Web service.

Any ideas? My resultFormat is object.

Thanks.
