    Web service via SOAP / HTTP and MS SQL Server 2005: no data output

    Smily1979 Level 1
      Hello Flex developer.

      I have a small problem and hope you can help me.


      I'm developing a website that retrieves information from a SQL Server 2005 database / tables und visualize them.
      Getting access to these data, I provide stored procedures in the SQL Server. With the help of SQL Server 2005, these procedures are allocated as web service. The displaying information are the table entries. I do not want to exchange documents with the SQL Server.

      The SQL Server deliver a WSDL file via a specific URL. the Web Service itself works, because I tested it with the program "XML Spy".

      Now, my Code in detail, that I modified using the <mx:WebService> tag. In the following, you see the table definition, where zhe information should be displayed.

      <mx:DataGrid id="sqlServerWebServiceGrid" x="10" y="328" width="566" height="139">

      Definition of the Service:

      <mx:WebService id="sqlServerWebService" wsdl=" http://<serverName>/Server Objects/Endpoints/SOAP?WSDL">
      <mx:operation name="ReportList" result="sqlServerResult(event)">
      <startTime>2006-01-01 00:00:00</startTime>
      <stopTime>2008-01-01 00:00:00</stopTime>

      A Button acting as an activator for my call:

      <mx:Button x="10" y="600" label="callWeb Service" click="callServices()"/>

      At the end my script part:

      /* the function calls the Web service */
      private function callServices():void{


      /* the function transmit the result to the datagrid*/
      private function sqlServerResult(event:ResultEvent):void{
      sqlServerWebServiceGrid.dataProvider = (event.result as ArrayCollection);

      Now my real problem: That is the error message I get before arriving 'sqlServerResult' in my function:

      [RPC Fault faultString="Error #1023: Stapelüberlauf." faultCode="DecodingError" faultDetail="null"]

      at flash.events::EventDispatcher/dispatchEvent()
      at flash.net::URLLoader/onComplete()

      Advice: 'Stapelüberlauf' stands for stack overflow.

      Does anybody have an idea to solve the problem or where the error is located?
