Problems using LiveCycle Designer and Web Services

Question

Hi there.
I've just finished reading all the 485 post in this forum, and I've already looked at all the samples and FAQ's, but I still I have the same problem, and it seems I'm not the only one. Here goes:
I have a .NET Web Service that exposes three methods: one that indicates which PDF to open, one to pre-populate some of the fields of the form and another one to handle the submitted form.
The first method is called within my asp.net web application and simply determines which pdf form to open in a given context. This one is cool and I have no problems here.
The second method populates my pdf form. But here starts the trouble. I can't seem to make the pdf call the web service when it is loaded. I mean, what I want is to tell the pdf form that when he loads (and before he shows on the browser), he should call the web service method that pre-populates him. But I can't seem to be able to do this. I've seen JimmiPham's CheckCreditCard.pdf sample, but what he does is call the web service upon a click on the button. What I wanted is similar but on the load of the form. I've added the following line of javascript code to the initialize method of a textbox:
msg.rawValue = xfa.connectionSet.conn.execute(0);
where msg is the textbox and conn is the name of my connection. I've used this code based on the sample of the designer help. I've also tried to drag and drop the button from the dataview (the one that is automatically generated) but it wont work. If I press it it gives me an error stating that there was an error attempting to read the web service file (*.asmx).
I've also tried to drag and drop the textbox in the generated web service response (in the dataview) but nothing works.
Does anyone have any ideas of what am I doing wrong? This is my first contact with this technology, and I really don't know very well how to manipulate it...
Regards.

Hi Jimmy.<br /><br />Thanks for the help.<br />I'm getting really desperate now. Your sample doesn't work. However I have some more info that might bring some light into the fight...<br />I've seen your sample (awesome work), tried it and saved it. Then I opened it with designer 7.0 and checked the code in the click event of the button.<br />Then I copied/pasted your code into my form. I dragged a text box and a button into my form and left them with the default names (TextBox1 and Button1). In the click event of Button1 I've pasted your code and then changed the parts I wanted, as follows:<br /><br />----- form1.#subform[0].Button1::click - (JavaScript, client) --------------------------------------<br />var cWSURL = "http://localhost/SIIOP.PDFManager/PDFManager.asmx?WSDL";<br /><br />app.alert("Setup webservicex PopulatePDF Interface using WSDL URL: \"" + cWSURL + "\"\n");<br /><br />SOAP.wiredump = true;<br /><br />var service = SOAP.connect(cWSURL);<br /><br />if(typeof service != "object")<br />     app.alert("Couldn't get PopulatePDF WSDL object");<br /><br />if(service.PopulatePDF == "undefined")<br />     app.alert("Couldn't get webservicex.PopulatePDF Call");<br /><br />var e;<br /><br />// I need no parameters<br />//var param =<br />//{<br />//    "CardNumber": xfa.resolveNode("CardNumber").rawValue<br />//};<br /><br />try<br />{<br />    app.alert("Make PopulatePDF SOAP call");<br />     <br />//     var result = service.CheckCC(param);<br />     var result = service.PopulatePDF();<br /><br />     if((result == "") || (result == null))  {<br />          app.alert("WebService PopulatePDF returns nothing");<br />         result = "<no results returned>";<br />          }<br /><br />function dump(obj)<br />{<br /><br />    if(typeof obj == "object")<br />    {<br />        for(var i in obj)<br />        {<br />             app.alert("note1: " + i + " = " + obj[i]);<br />             if (i == "string")<br />               {<br />                    xfa.form.Page1.TextField1.rawValue = obj[i];<br />               }<br />          }<br />    }<br />    else app.alert("note2: " + i + " = " + obj[i]);<br />}<br /><br />dump(result);<br /><br />SOAP.wiredump = false;<br /><br />     //xfa.datasets.data.loadXML(result);<br />     //xfa.resolveNode("CardType").rawValue = result["urn:schemas-microsoft-com:xml-diffgram-v1diffgram"]["NewDataSet"]["Table"].CardTy pe;<br />     //xfa.resolveNode("CardValid").rawValue = result["urn:schemas-microsoft-com:xml-diffgram-v1diffgram"]["NewDataSet"]["Table"].CardVa lid;<br /><br />}<br />catch(e)<br />{<br />     app.alert("Problem with webservicex.PopulatePDF Call: " + e);<br />}<br /><br />I saved the form and opened it with internet explorer. When I press the button, I get the first alert stating that "Setup webservicex PopulatePDF Interface using WSDL URL: http://localhost/SIIOP.PDFManager/PDFManager.asmx?WSDL". That's correct.<br />Then I get an alert that says "Couldn't get PopulatePDF WSDL object", which means that he can't get the object. The result is undefined. But that's odd, since I can establish a data connection to this WSDL using the New Data Connection wizard, and in this wizard it even says which methods and actions the web service has... So, the problem must be in the way the web service exposes himself to the PDF, right? <br />Well anyway, here follows the wsdl I have:<br /><br /> <?xml version="1.0" encoding="utf-8" ?> <br />- <wsdl:definitions xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:s="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://tempuri.org/" xmlns:tm="http://microsoft.com/wsdl/mime/textMatching/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" targetNamespace="http://tempuri.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"><br />- <wsdl:types><br />- <s:schema elementFormDefault="qualified" targetNamespace="http://tempuri.org/"><br />- <s:element name="PopulatePDF"><br />  <s:complexType /> <br />  </s:element><br />- <s:element name="PopulatePDFResponse"><br />- <s:complexType><br />- <s:sequence><br />  <s:element minOccurs="0" maxOccurs="1" name="PopulatePDFResult" type="s:string" /> <br />  </s:sequence><br />  </s:complexType><br />  </s:element><br />- <s:element name="CallPDF"><br />  <s:complexType /> <br />  </s:element><br />- <s:element name="CallPDFResponse"><br />- <s:complexType><br />- <s:sequence><br />  <s:element minOccurs="0" maxOccurs="1" name="CallPDFResult" type="s:string" /> <br />  </s:sequence><br />  </s:complexType><br />  </s:element><br />- <s:element name="HandleSubmittedPDF"><br />  <s:complexType /> <br />  </s:element><br />- <s:element name="HandleSubmittedPDFResponse"><br />- <s:complexType><br />- <s:sequence><br />  <s:element minOccurs="0" maxOccurs="1" name="HandleSubmittedPDFResult" type="s:string" /> <br />  </s:sequence><br />  </s:complexType><br />  </s:element><br />  </s:schema><br />  </wsdl:types><br />- <wsdl:message name="PopulatePDFSoapIn"><br />  <wsdl:part name="parameters" element="tns:PopulatePDF" /> <br />  </wsdl:message><br />- <wsdl:message name="PopulatePDFSoapOut"><br />  <wsdl:part name="parameters" element="tns:PopulatePDFResponse" /> <br />  </wsdl:message><br />- <wsdl:message name="CallPDFSoapIn"><br />  <wsdl:part name="parameters" element="tns:CallPDF" /> <br />  </wsdl:message><br />- <wsdl:message name="CallPDFSoapOut"><br />  <wsdl:part name="parameters" element="tns:CallPDFResponse" /> <br />  </wsdl:message><br />- <wsdl:message name="HandleSubmittedPDFSoapIn"><br />  <wsdl:part name="parameters" element="tns:HandleSubmittedPDF" /> <br />  </wsdl:message><br />- <wsdl:message name="HandleSubmittedPDFSoapOut"><br />  <wsdl:part name="parameters" element="tns:HandleSubmittedPDFResponse" /> <br />  </wsdl:message><br />- <wsdl:portType name="PDFManagerSoap"><br />- <wsdl:operation name="PopulatePDF"><br />  <wsdl:input message="tns:PopulatePDFSoapIn" /> <br />  <wsdl:output message="tns:PopulatePDFSoapOut" /> <br />  </wsdl:operation><br />- <wsdl:operation name="CallPDF"><br />  <wsdl:input message="tns:CallPDFSoapIn" /> <br />  <wsdl:output message="tns:CallPDFSoapOut" /> <br />  </wsdl:operation><br />- <wsdl:operation name="HandleSubmittedPDF"><br />  <wsdl:input message="tns:HandleSubmittedPDFSoapIn" /> <br />  <wsdl:output message="tns:HandleSubmittedPDFSoapOut" /> <br />  </wsdl:operation><br />  </wsdl:portType><br />- <wsdl:binding name="PDFManagerSoap" type="tns:PDFManagerSoap"><br />  <soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document" /> <br />- <wsdl:operation name="PopulatePDF"><br />  <soap:operation soapAction="http://tempuri.org/PopulatePDF" style="document" /> <br />- <wsdl:input><br />  <soap:body use="literal" /> <br />  </wsdl:input><br />- <wsdl:output><br />  <soap:body use="literal" /> <br />  </wsdl:output><br />  </wsdl:operation><br />- <wsdl:operation name="CallPDF"><br />  <soap:operation soapAction="http://tempuri.org/CallPDF" style="document" /> <br />- <wsdl:input><br />  <soap:body use="literal" /> <br />  </wsdl:input><br />- <wsdl:output><br />  <soap:body use="literal" /> <br />  </wsdl:output><br />  </wsdl:operation><br />- <wsdl:operation name="HandleSubmittedPDF"><br />  <soap:operation soapAction="http://tempuri.org/HandleSubmittedPDF" style="document" /> <br />- <wsdl:input><br />  <soap:body use="literal" /> <br />  </wsdl:input><br />- <wsdl:output><br />  <soap:body use="literal" /> <br />  </wsdl:output><br />  </wsdl:operation><br />  </wsdl:binding><br />- <wsdl:service name="PDFManager"><br />  <documentation xmlns="http://schemas.xmlsoap.org/wsdl/" /> <br />- <wsdl:port name="PDFManagerSoap" binding="tns:PDFManagerSoap"><br />  <soap:address location="http://localhost/SIIOP.PDFManager/PDFManager.asmx" /> <br />  </wsdl:port><br />  </wsdl:service><br />  </wsdl:definitions><br /><br />If I invoke this webservice method through Internet Explorer, I get the following response:<br /><br />  <?xml version="1.0" encoding="utf-8" ?> <br />  <string xmlns="http://tempuri.org/">Hello World</string>
