Hi Tracy,
Here is what I found in Flex SDK source. I hope it will clarify the
event.result mystery a bit:
flex_sdk_3/frameworks/projects/rpc/src/mx/rpc/soap/SOAPDecoder.as
Line 306:
else if (resultFormat == "e4x")
{
// Return the children as an XMLList.
soapResult.result = bodyXML.children();
}
When I run my application in the Flex debugger (I use fdb here), I see
that event.result is XMLList:
Breakpoint 23, decodeEnvelope() at SOAPDecoder.as:285
285 var bodyXML:XML =
responseXML[soapConstants.bodyQName][0];
(fdb) n
287 if (bodyXML == null || bodyXML.hasComplexContent()
== false || bodyXML.children().length() <= 0)
(fdb)
294 var faultXMLList:XMLList =
bodyXML[soapConstants.faultQName];
(fdb)
295 if (faultXMLList.length() > 0)
(fdb)
302 if (resultFormat == "object")
(fdb)
306 else if (resultFormat == "e4x")
(fdb)
309 soapResult.result = bodyXML.children();
So, when I print event.result in my result handler, I see
(fdb) p *event.result
$1 = result = [Object 159761505, class='XMLList']
0 = [Object 160100257, class='XML']
I wish I had XML class source code. It would be interesting to look
how XML() is implemented. It is defined in Global.as, but no actual
source is there:
public native function XML(expression:Object):XML
