I seem to be missing something. I tried the suggested way:
public function loginHandler(e:ResultEvent):void {
userData = e.result as ArrayCollection;
var object:Object = userData.getItemAt(0) ;
var firstName:String = object["FIRSTNAME"] ;
Alert.show(firstName);
}
and I am getting this error:
TypeError: Error #1009: Cannot access a property or method of a null object
reference.

How can I
change my backend script a bit in order to return an
ArrayCollection of typed User objects? Any examples?
Also, I normally don't return all user info, but just using '*' till I can get
this figured out:
Thanks for the help so far

Try the following:
userData:ArrayCollection = event.result as ArrayCollection ;
Then it seems that the array contains untyped object (Dictionary/hashmap type)
so:
userData.getItemAt(0)["FIRSTNAME"] should give you :"Wally" ;
do not have a compiler in hand at the moment ... if the previous line does not
work for any reason:
var object:Object = userData.getItemAt(0) ;
var firstName:String = object["FIRSTNAME"] ;
PS: I would recomment to change your backend script a bit in order to return an
ArrayCollection of typed User objects
PS2: Passwords are normally kept on the server and not transfered on the client
, at least not in text form...

Using Alert.show(ObjectUtil.toString(e.result)) This is what I got:
(mx.collections::ArrayCollection)#0
filterFunction = (null)

source = (Array)#2
[0] (Object)#3

How can I set it to userData:ArrayCollection and then call the firstName
variable?

Why do not you try Alert.show(ObjectUtil.toString(e.result)) //replace e.result
with e to see the whole event
ObjectUtil is very useful in situation like this as it show a textual
representation of any object graph

Perhaps you have an arrayCollection of arrayCollections (What does the
debugger show as the result type?). You may like to try...
var resultArrColl:ArrayCollection = e.result.source;
var firstResult:ArrayCollection = resultArrColl[0];
Alert.show(firstResult[0]);
