    Alert problem

    Hi guys! I have a problem with an Alert
    I connected my phone with a database using a servlet. I would like that while it is trying to connect with the database, it will show an Alert with a gauge.

    this is the code:

    private void infoAlert(Display display)
    Alert info = new Alert("Information","Connecting to the server", null, null);
    Gauge indicator = new Gauge (null,false,Gauge.INDEFINITE,Gauge.CONTINUOUS_RUNNING);

    I call this method when i try to connect the phone with the server:

    http = (HttpConnection) Connector.open(url);
    if (http.getResponseCode() == HttpConnection.HTTP_OK)
    byte servletData[]=null;
    input = http.openInputStream();
    int length = (int) http.getLength();

    if (length > 0)

    servletData = new byte[length];

    when I get back the data from the server the display will show the form that contains them

    It work on the emulator but on my phone it doesn't work and i got this exception: java.lang.IllegalArgumentException: Alert cannot return to Alert

    I also tryied info.setTimeout(5000);
    but it doesn't work!!!!

    please could someone help me???? Tell me where I do some mistake or tell me some other way to do it??

    Re: Alert problem

    Instead of setCurrent(Alert), you should use
    setCurrent(Alert alert, Displayable nextDisplayable)
    Requests that this Alert be made current, and that nextDisplayable be made current after the Alert is dismissed.
