Hi,
For export file in format XML, TXT, ...
continue steps
1) create node with name  FileResource and type binary
2) create view and add control filedownload and properties control set data binding node FileResource
3) create following code
  //@@begin javadoc:wdDoInit()
    /** Hook method called to initialize controller. */
  //@@end
  public void wdDoInit()
    //@@begin wdDoInit()
        IWDAttributeInfo attInfo = wdContext.getNodeInfo().getAttribute(IPrivateExportListView.IContextElement.FILE_RESOURCE);
        IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) attInfo.getModifiableSimpleType();  
        binaryType.setFileName(ExportListView.FILE_NAME);
        binaryType.setMimeType(WDWebResourceType.TXT);
        try {
            String resourcePath = WDURLGenerator.getResourcePath(wdComponentAPI.getDeployableObjectPart(), ExportListView.FILE_NAME);
            wdContext.currentContextElement().setFileResource(this.getByteArrayFromResourcePath(resourcePath));
        } catch (WDAliasResolvingException e) {
            wdComponentAPI.getMessageManager().reportException(e.getLocalizedMessage(), true);
        } catch (Exception e) {
            throw new WDRuntimeException(e);
    //@@end
and add following code
  //@@begin others
    private byte[] getByteArrayFromResourcePath(String resourcePath) throws FileNotFoundException, IOException {
        FileInputStream in = new FileInputStream(new File(resourcePath));
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        int length;
        String Prueba = "hola esto es una prueba" + new Date().getSeconds();
        //byte[] part = new byte[10 * 1024];
        byte[] part = Prueba.getBytes();
        while ((length = in.read(part)) != -1) {
            out.write(part, 0, length);
        out.write(Prueba.getBytes());
        in.close();
        return out.toByteArray();
    // store image file name in constant FILE_NAME
    private static final String FILE_NAME = "doc.txt";
  //@@end
4)Create file ext(txt,xml,...) in following dir of the project
