Creating an HTTPService not through a tag
is not officially supported right now. I don’t remember if not calling
initialized will actually hurt you, mostly it would screw up validation if you had
any but I think it should be OK. The bigger problem is that you’re
trying to access the result too quickly. You need to do it in a result handler
(addEventListener(“result”)) since the call is asynchronous. Don’t
forget to use Delegates.

Subject: [flexcoders] Instantiate
an HTTPService object in ActionScript
I am trying to create a custom component to manage
my Web Services.
So far I have created a class that contains a
variable of type
mx.servicetags.HTTPService as follows:
class DataManager extends Object{
public var
requestService:mx.servicetags.HTTPService;
public function
ASDataManager(){
super();
// mx.servicetags.HTTPService.initialize()
requestService = new
mx.servicetags.HTTPService()
requestService.url
= "http://bheitstuman03/GBOS/ObjectService.asmx/requestObjects"
requestService.method = "get"
requestService.resultFormat = "object"
var params:Object = new Object()
params.objectXML = ""
params.credentials =
"UserBob;BobsPassword"
requestService.request = params
requestService.addEventListener("fault",
this.handleFault);
}
public function
getData(){
requestService.send()
var test:Object
test = requestService.result
}
public function
handleFault(event):Void{
trace("Send Fault");
}
}
However, when I create an instance of this above
DataManager and
call the getData method, it doesn't work.
After stepping through
the code, I noticed that it does call the
HTTPService's send method
but the local _document variable has no
value. I also noticed that
the initialized function sets this variable's
value as follows:
public function initialized(document : Object, id
: String) : Void
{
_id =
id;
_document = document;
}
Does anyone know how to instantiate a working
HTTPService object
within ActionScript?
