Error while loading an XML document using a structured application

Question

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
        opened so this shouldn't be a problem if the application to be used is
        listed in the structapps.fm file.*/
        var retParm = new PropVals()
        var fileObj = Open(filename, params, retParm);
        return fileObj
    } else {
        return null;

Pierre,
Depending on the object "myLastFile", the method openDlg might not even exist (if the myLastFile object is not a File object, for instance). And I do not see any need for the myLastFile anyhow, as you are presenting a dialog to select a file to open. I recommend using the global ChooseFile( ) method instead. This will give you a filename as string in full path notation, or null when no file was selected in the dialog. I am not sure what your ExtendScript documentation states about the return value for ChooseFile, but if that differs from what I am telling you here, the documentation is wrong. So, if you replace the first lines of your code with the following it should work:
function openXMLFile ( ) {
    var filename = ChooseFile ( "Choose XML file ...", "", "*.xml", Constants.FV_ChooseSelect );
While writing this, I see that Russ has already given you the same advice. Use the symbolic constant value I indicated to use the ChooseFile dialog to select a single file (it can also be used to select a directory or open a file - but you want to control the opening process yourself). Note that this method allows you to set a start directory for the dialog (second parameter). The ESTK autocompletion also gives you a fifth parameter "helplink" which is undocumented and can safely be ignored.
Good luck
