Interesting. It looks like you are correct, that the base type in e4x resultFormat is XMLList.
The acutal data returned, however is a normal xml node. I plan to stick with using XML() to receive my results.

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 - Mykola --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Tracy Spratt" <[EMAIL PROTECTED]> wrote: > > Odd that the "as" operator is not working correctly for you. > > > > I'd use the XML() syntax.
