In a Flex application I am trying to turn an Object into a QueryString such as name1=value1&name2=value2... But I am having trouble getting the names of the Objects children. How do I enumerate the names instead of the values?
Thanks

I'm guessing you're doing a for each(in) loop. Just do a normal for(in) loop and you'll get the names instead of the values:
for(var name:String in obj) {
var value:* = obj[name];
// do whatever you need
}

If it's a concrete class instead of just an Object, see ObjectUtil.getClassInfo()

I believe
for(in) still works on concrete classes, but it's generally more limited on what it returns. It will only pick up what those classes have set up as visible using the setPropertyIsEnumerable method.Ok, first off, if you need that query string to actually query a server, you don't really need to get it yourself as this code will query the server for you
protected function callSerivce():void
{
var o:Object = new Object();
o.action = "loadBogusData";
o.val1 = "dsadasd";
service.send(o);
}
<mx:HTTPService id="service" url="http://www.somewhere.com/file.php" method="GET" showBusyCursor="true"/>
Will make a call to the server like this: http://www.somewhere.com/file.php?action=loadBogusData&val1=dsadasd
But in case you really want to analyze the object by hand, try using ObjectUtil.getClassInfo, it returns a lot of information including all the fields (read more on LiveDocs).
