Flex Builder 3 - Web Service Proxy Generator

Question

Hi guys,
I am investigating the web service proxy generator that is part of FB3. I can't seem to get it working properly and wondered if anyone else has managed to succeed.
I am using WSDL files that are generated from RFC-enabled function modules using the web service browser on a WAS ABAP.
I have chosen two quite simple function modules. RFC_SYSTEM_INFO and BAPI_USER_GETLIST.
The WSDL files are retrieved from the URLs /sap/bc/soap/wsdl11?services=RFC_SYSTEM_INFO and /sap/bc/soap/wsdl11?services=BAPI_USER_GETLIST on my server.
I am following the Adobe documentation at http://livedocs.adobe.com/flex/3/html/help.html?content=data_4.html#151327
Anyway, I generate the proxies and then try to use them.
First I call the RFC_SYSTEM_INFO web service like this...
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:ws="au.com.yelcho.*">
    <ws:RFC_SYSTEM_INFOService id="myWebService" />
     <mx:Button label="Call Web Service" labelPlacement="top" click="myWebService.rFC_SYSTEM_INFO_send()" x="97" y="10"/>     
     <mx:Label x="60" y="43" text="Current Resources"/>
     <mx:Text id="txNameOutput1" text="{myWebService.rFC_SYSTEM_INFO_lastResult.CURRENT_RESOURCES}" x="185" y="43"/>
     <mx:Label x="54" y="69" text="Maximal Resources"/>
     <mx:Text id="txNameOutput" text="{myWebService.rFC_SYSTEM_INFO_lastResult.MAXIMAL_RESOURCES}" x="185" y="69"/>
     <mx:Label x="105" y="95" text="RFC HOST"/>
     <mx:Text id="txNameOutput2" text="{myWebService.rFC_SYSTEM_INFO_lastResult.RFCSI_EXPORT.RFCHOST}" x="185" y="95"/>
</mx:Application>
At first glance this seems to work, but on closer inspection it turns out that not all the returned XML payload has been extracted properly.
Attributes at the top level, like CURRENT_RESOURCES work fine. Attributes at a lower level, like RFCSI_EXPORT.RFCHOST are empty.
It is even more difficult when I try and call the BAPI_USER_GETLIST service because it requires input parameters. Testing with XMLSpy I found that I need to pass the MAX_ROWS and USERLIST parameters to get the SOAP call to work.
I have been unable to figure out how to pass these parameters so that the web service call takes place properly. I have tried using both the MXML and ActionScript methods.
It is entirely probably that, as I haven't played with Flex for some months, I have forgotten some vital piece of information on how to do this.
Any help would be appreciated.

Hi Raja,
thanks for your ongoing help with this, but you have confused me again - notr a hard this to do.
When I generate the proxies from BAPI_USER_GETLIST I get the following .as files created..
BAPIRET2.as
BAPIUSNAME.as
BAPIUSSEXP.as
BAPIUSSRGE.as
BAPI_USER_GETLISTResultEvent.as
BAPI_USER_GETLISTService.as
BAPI_USER_GETLIST_request.as
BaseBAPI_USER_GETLISTService.as
BaseBAPI_USER_GETLISTServiceSchema.as
FIELD_type0.as
FIELD_type1.as
FIELD_type2.as
FIELD_type3.as
FIELD_type4.as
FIELD_type5.as
FIRSTNAME_type0.as
FIRSTNAME_type1.as
FULLNAME_type0.as
FULLNAME_type1.as
HIGH_type0.as
HIGH_type1.as
HIGH_type2.as
HIGH_type3.as
IBAPI_USER_GETLISTService.as
ID_type0.as
ID_type1.as
LASTNAME_type0.as
LASTNAME_type1.as
LOGOP_type0.as
LOGOP_type1.as
LOG_MSG_NO_type0.as
LOG_MSG_NO_type1.as
LOG_NO_type0.as
LOG_NO_type1.as
LOW_type0.as
LOW_type1.as
LOW_type2.as
LOW_type3.as
MESSAGE_type0.as
MESSAGE_type1.as
MESSAGE_V1_type0.as
MESSAGE_V1_type1.as
MESSAGE_V2_type0.as
MESSAGE_V2_type1.as
MESSAGE_V3_type0.as
MESSAGE_V3_type1.as
MESSAGE_V4_type0.as
MESSAGE_V4_type1.as
NUMBER_type0.as
NUMBER_type1.as
OPTION_type0.as
OPTION_type1.as
OPTION_type2.as
OPTION_type3.as
PARAMETER_type0.as
PARAMETER_type1.as
PARAMETER_type2.as
PARAMETER_type3.as
PARAMETER_type4.as
PARAMETER_type5.as
RETURN_type0.as
RETURN_type1.as
SELECTION_EXP_type0.as
SELECTION_EXP_type1.as
SELECTION_RANGE_type0.as
SELECTION_RANGE_type1.as
SIGN_type0.as
SIGN_type1.as
SYSTEM_type0.as
SYSTEM_type1.as
TYPE_type0.as
TYPE_type1.as
USERLIST_type0.as
USERLIST_type1.as
USERNAME_type0.as
USERNAME_type1.as
WITH_USERNAME_type0.as
WITH_USERNAME_type1.as
So my question is where do the datatypes...
              TABLE_OF_BAPIRET2;
               TABLE_OF_BAPIUSSEXP;
               TABLE_OF_BAPIUSSRGE;
               TABLE_OF_BAPIUSNAME;
               TABLE_OF_BAPIUSNAME;
...come from?
Is your proxy generator creating something mine isn't or did you create these yoursefl?
