Error while loading an XML document using a structured application

Hi,

I try to load an XML document using a structured application defined in the default structapps.fm

My code is shown down, extracted from the FDK API code sample.

Problem, I always have the same message :

"Cannot find the file named e:\xml\AdobeFrameMaker10\file. Make sure that the file exists. "

Where "e:\xml\AdobeFrameMaker10\" is my install directory.

So I assume that frame try to find the structapps.fm file but does not find it.

What else can it be ?

Does anyone knowns how to achieve this simple task using extendScript ?

Thanks for any comments, Pierre

function openXMLFile(myLastFile) {

    var filename = myLastFile.openDlg("Choose XML file ...", "*.xml", false);

    if (filename != null) {

        /* Get default open properties. Return if it can’t be allocated. */

        var params = GetOpenDefaultParams();

        /* Set properties to open an XML document*/

        /*Specify XML as file type to open*/

        var i = GetPropIndex(params, Constants.FS_OpenAsType)

        params[i].propVal.ival = Constants.FV_TYPE_XML;

        /* Specify the XML application to be used when opening the document.*/

        i = GetPropIndex(params, Constants.FS_StructuredOpenApplication)

        params[i].propVal.sval = "myApp";

        i = GetPropIndex(params, Constants.FS_FileIsOldVersion)

        params[i].propVal.ival = Constants.FV_DoOK

        i = GetPropIndex(params, Constants.FS_FontNotFoundInDoc)

        params[i].propVal.ival = Constants.FV_DoOK

        i = GetPropIndex(params, Constants.FS_FileIsInUse)

        params[i].propVal.ival = Constants.FV_DoCancel

        i = GetPropIndex(params, Constants.FS_AlertUserAboutFailure)

        params[i].propVal.ival = Constants.FV_DoCancel

        /*The structapps.fm file containing the specified application must have

        already been read. The default structapps.fm file is read when FrameMaker is

        var retParm = new PropVals()

        var fileObj = Open(filename, params, retParm);

        return fileObj

    } else {

        return null;
