Populate Flex ComboBox from XML from PHP - php

Question

I'm having trouble populating a combobox from an XML response. Here is the XML that I am receiving:
<distros>
<entry>
<distro>CentOS</distro>
<distro>Debian</distro>
<distro>Other</distro>
<distro>Sabayon</distro>
<distro>Ubuntu</distro>
<distro>VMware</distro>
<distro>Windows</distro>
</entry>
</distros>
So probably the most basic form of XML ever!
and here is the flex code:
private function getDistros():void
{
httpReq = new HTTPService;
httpReq.url = 'http://myserver/xml.php';
httpReq.resultFormat = 'e4x';
httpReq.method = 'GET';
httpReq.addEventListener(ResultEvent.RESULT, popDistros);
httpReq.send( null );
}
private function popDistros(event:ResultEvent):void
{
if(event.result != "")
{
// Set the data to the XMLListCollection for lookup
myXmlCollection= new XMLListCollection(event.result.entry);
// Bind the ListCollection to the comboBox
Alert.show(myXmlCollection.toString());
distroCombo.dataProvider = myXmlCollection.toString();
}
}
and the MXML:
<mx:ControlBar x="139" y="10" width="266" height="358" verticalAlign="top" horizontalAlign="left" direction="vertical">
<mx:ComboBox id="distroCombo" labelField="distro"></mx:ComboBox>
<mx:ComboBox id="imageCombo"></mx:ComboBox>
<mx:Button label="Download"/>
</mx:ControlBar>
The XML comes back fine in the Alert but the comboBox won't populate and I have tried this so many different ways now, anyone got any suggestions? Have I just been staring at it far too long?

Answer 1

if the result (event.result) is XML, then It should wotk like this: (it differs with .distro in the end compared to yours)
myXmlCollection = new XMLListCollection(event.result.entry.distro);
...this should create valid data in myXmlCollection
But then also this row is wrong:
distroCombo.dataProvider = myXmlCollection.toString();
it creates just one item in dataProvider of type string, (Just BTW: if you would have used spark combobox, you would have get compile error at this row).
just use this instead:
distroCombo.dataProvider = myXmlCollection;
And also note, that you can see correct result in the Alert, but it does not say if the data are of correct type, coz Alert evertyhing converts to string :)
