Hi Tim; Thanks for your reply. I'm not sure that we're experiencing exactly the same problem. As far as I know, our web server (ASP .NET) does not rely on the order of parameters in the SOAP envelope.
The problem for us is that the values passed to the server are being placed in the wrong SOAP parameters. For example, here is the incorrect SOAP envelope that results in a web service fault: <SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";><SOAP-ENV:Body><CreateView xmlns="http://www.kodak.com/WPE/Galiano/";><ns0:SessionId xmlns:ns0="http://www.kodak.com/WPE/Galiano/";></ns0:SessionId><ns0:Query xmlns:ns0="http://www.kodak.com/WPE/Galiano/";>AB4AB4A8-28C8-A580-B12B-FF FFFFFF48A3</ns0:Query></CreateView></SOAP-ENV:Body></SOAP-ENV:Envelope> And here is the correct envelope (no code changes -- just a different run of the application ): <SOAP-ENV:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/";><SOAP-ENV:Bod y><CreateView xmlns="http://www.kodak.com/WPE/Galiano/";><ns0:Query xmlns:ns0="http://www.kodak.com/WPE/Galiano/";></ns0:Query><ns0:SessionId xmlns:ns0="http://www.kodak.com/WPE/Galiano/";>8C428366-587C-D759-DD7B-FF FFFFFF6CF8</ns0:SessionId></CreateView></SOAP-ENV:Body></SOAP-ENV:Envelo pe> Look at the <Query> and <SessionId> parameters. In the first example, <SessionID> is blank, and <Query> contains a UID. In the second example, <SessionID> contains a UID, and <Query> is blank. While it's true that the order of the parameters has been swapped, it's the fact that the values for the parameters were not also swapped that is causing the trouble. I suppose I could change the web-service prototype to take a single, complex object, but I'd rather not have to alter the server implementation to fix what seems to be a bug in the client framework. Is there a different way of defining the parameters and values for a SOAP web service invocation? Ideally, I would create a dictionary with SessionID and Query attributes, set the value of those attributes and attach it to the web service call. I don't see anything in the WebServices APIs that would let me do that though.

We were told that doc/lit support was a bit flaky in Flex 2. We solved it by changing our webservice (we use jibx-soap to a Java back end) to be unordered.
