You are mixing up the XML implementation versions.

 

XMLDocument and simpleDecoder are legacy AS2 classes, included in AS3 only
for backwards compatibility.

 

You cannot use them with XML() which is an e4x implementation.

Interesting that it works once, but second call to this function generates
the error.

Thanks Pete. Adding makeObjectsBinadble=false solved the problem. Yes, the service returns a simple XML generated from a cfm file.
userPrefdevicephone/device/userPref
I'm curious to know how this is related to the stack overflow. Does makeObjectsBinadble=false restrict any functionality ? - since i need the included swf to communicate with the loader swf and also with the hosting HTML page (via some callbackjs fns).

Out of curiosity, does your HTTPService return XML? If so, any chance you could show us what the XML looks like? As a work around for now you could either set makeObjectsBinadble=false on your HTTPService tag or set resultFormat=e4x or resultFormat=text (instead of the default, which is object).


Thanks,
 Pete

HI,

I'm trying to include an swf file (generated from FlexBuilder) within another swf file using mx:image. The included file is located on a different server, and the include works fine. Now, if a HTTPService is added to the included file, the call fails with the following exception.

It appears like an infinite loop that's triggered internally and terminates with a stack overflow.

RE: [flexcoders] Stack Overflow in swf to swf include

2006-10-18 Thread Peter Farland






It does restrict some functionality... 
to describe what's happening in HTTPService - an 
underlyingURLLoader returns your XML data as a String. This String is then 
turned into XML and then if the resultFormat is left as the default setting of 
"object" it will convert this XML into an ActionScript Object graph. If 
makeObjectsBindable is false thenObjects will not be wrapped 
by mx.utils.ObjectProxy and Arrays will not be wrapped by 
mx.collections.ArrayCollection and as such property change events will not be 
dispatched when the object graph is modified, which will mean if the data is 
used as a data provider to a UI component it won't reflect changes as the data 
is modified.

Another workaround for now is to do the decoding 
yourself. You could either change the resultFormat attribute to E4X and then 
process the XML structure into a tree of objects or specify a Function for the 
xmlDecode property. Some code to demonstrate the general idea is 
below:

import 
mx.collections.ArrayCollection;
import 
mx.utils.ObjectProxy;

...

 private function 
decode(data:XML):Object 
{ var 
result:Object;

 if 
(data.elements().length() == 0) 
{ result = 
data.text().toXMLString(); 
} 
else 
{ result = 
{}; result 
= new 
ObjectProxy(result); 
var elements:XMLList = data.elements();

 
for each (var x:XML in 
elements) 
{ 
var part:Object = decode(x);

 
var name:String = 
x.localName(); 
var existing:Object = 
result[name]; 
if (existing != 
null) 
{ 
if (existing is ArrayCollection)
 
ArrayCollection(existing).addItem(part);
 
else
 
{
 
var temp:ArrayCollection = new ArrayCollection();
temp.addItem(existing);
temp.addItem(part);
 
result[name] = temp;
} 
} 
else 
{ 
result[name] = 
part; 
} 
} }

 return 
result; }

2006-10-18 Thread Peter Farland






Hmm, on testing this code in your scenario I realized I can 
reproduce the issue again that you described. It seems related to ObjectProxy's 
use of the intrinsic Proxy class from ActionScript. If you could 
avoid checking for existing properties and develop another way to detect what 
needs to be an Array then you can avoid the bug... otherwise you will need to 
avoid the use of ObjectProxy in this scenario for now.

Note the bug that was filed was 188654 if you need to refer 
to it in the future.
