I'm trying to display a dialog when user attempts to download something, but when the dialog is dismissed, the app redirects back to an earlier form page. The download works but the next form does not; just keeps displaying a 'Loading' dialog and returning to the previous form.
The looping form was commented out of the code below..
ConnectionRequest request = new ConnectionRequest();
// InfiniteProgress ip = new InfiniteProgress();
// Dialog dlg = ip.showInifiniteBlocking();
// request.setDisposeOnCompletion(dlg);
Hashtable param_data_url = new Hashtable();
param_data_url.put("index", 0);
param_data_url.put("rango", 10);
param_data_url.put("ciudad_id", Constants.CodigoCiudadActual);
String urlBusqueda = Constants.URL_SERVICIO_SHOW_PRODUCTOS_ADOM_MOVIL;
String url_conexion = Constants.getUrlServicio(Constants.URL_SERVIDOR_APLICACION, Constants.URL_APLICACION, urlBusqueda, param_data_url);
request.setUrl(url_conexion);
request.addResponseListener(new ActionListener() {
public void actionPerformed(ActionEvent evt) {
NetworkEvent netEvt = (NetworkEvent) evt;
byte[] dataArray = (byte[]) netEvt.getMetaData();

Your indentation and block of code makes this almost impossible to read and you cut off the top of the call so its impossible to really know. However, since you return from some sort of method and return a value I'm assuming your logic incorrectly expects synchronous behavior where addToQueue is asynchronous.
Try changing addToQueue into addToQueueAndWait.
