I've been playing with a project that was all html/php based.
I was able to set up a nice Flex 2 IU and hook it up to my back end
database without much trouble. I get xml records from an http
dataprovider and have some text fields and some datagrids. What I
want to do, though, is be able to update the xml record and push it
back over http. The event.result I get back from the dataprovider
is type Object. I was thinking that I ought to be able to coerce it
into an XML object and bind my UI to it so I could add and remove
datagrid items from the XML.
I can't seem to figure out how to do anything with the
event.result other than bind my UI to it. So how can I take xml
received over http and make it into an XML object I can bind to and
change ?
Here's what my provider and callback look like:
<mx:HTTPService
id="listingService"
url="
http://xxx.xxx.com/testdata.php" result="listingResult(event)"
method="POST">
<mx:request xmlns="">
<op>listsettings</op>
<account>{loginService.lastResult.userinfo.account}</account>
</mx:request>
</mx:HTTPService>
<mx:Script>
<![CDATA[
import mx.utils.XMLUtil
[Bindable]
var xmlData:XML;
import mx.rpc.events.ResultEvent;
import mx.utils.StringUtil;
public function getListing() : void {
listingService.send();
}
public function listingResult(event:ResultEvent) : void {
if(StringUtil.trim(String(event.result)) ==
String("FAILED"))
return;
xmlData = new XML(event.result);
}
]]>
</mx:Script>
