I need to repeat a small amount of code with 1 second delay
here is my code

public class ExampleChart extends ContentPanel{

    ArrayList<String> timeList = new ArrayList<String>();
    ArrayList<Long> queueSize = new ArrayList<Long>();
    private final ServerManagementAsync serverManagementSvc = GWT.create(ServerManagement.class);


   public ContentPanel createChart(final String customerId, boolean warrant){


       setHeading("Messages by domain");
       setFrame(true);
       setSize(550, 400);
       setLayout(new FitLayout());


       String url = "/gxt/chart/open-flash-chart.swf";
       final Chart chart = new Chart(url);


       chart.setBorders(true);
timeList = getTimeList(timeList);       
while (warrant){
           Timer t = new Timer(){
               public void run(){
                   ExampleChart ec = new ExampleChart();
                   AsyncCallback<Long> ac = new AsyncCallback<Long>() {
                       @Override
                       public void onFailure(Throwable throwable) {
                           //To change body of implemented methods use File | Settings | File Templates.
                       }


                       @Override
                       public void onSuccess(Long integer) {
                           timeList = getTimeList(timeList);
                           if (queueSize.size()<11){
                               queueSize.add(integer);
                           } else{
                               for (int i = 0; i<queueSize.size()-1; i++){
                                   queueSize.set(i,queueSize.get(i+1));
                               }
                           }
                           chart.setChartModel(getAreaChart(timeList, queueSize));
                           add(chart);
                           repaint();
                       }
                   };
                   serverManagementSvc.getMessageQueueSize(customerId, ac);
               }
           };
           t.schedule(2000);
       }
       chart.setChartModel(getAreaChart(timeList, queueSize));
       add(chart);
       repaint();
       return this;


    }


    public ArrayList<String> getTimeList(ArrayList<String> TimeList){
        ArrayList<String> timeList = TimeList;
        if (timeList.size() < 11){
            timeList.add(getCurrentTime());
        } else {
            for (int i = 0; i<timeList.size()-1; i++){
                timeList.set(i, timeList.get(i+1));
            }
            timeList.set(10, getCurrentTime());
        }
        return timeList;
    }


    public String getCurrentTime(){
        Date date = new Date();
        String hrs = Integer.toString(date.getHours());
        String min = Integer.toString(date.getMinutes());
        String sec = Integer.toString(date.getSeconds());
        return hrs + ":" + min + ":" + sec;
    }
    public ChartModel getAreaChart(ArrayList<String> dateList, ArrayList<Long> queueSize)
    {
        ChartModel cm = new ChartModel("Messages per domain", "font-size: 14px; font-family: Verdana;");
        cm.setBackgroundColour("#ffffff");
        XAxis xa = new XAxis();
        xa.setLabels(dateList);
        cm.setXAxis(xa);
        AreaChart area1 = new AreaChart();
        area1.setFillAlpha(0.3f);
        area1.setColour("#ff0000");
        area1.setFillColour("#ff0000");
        for (int n = 0; n<queueSize.size(); n++){
                area1.addValues(queueSize.get(n));
        }
        cm.addChartConfig(area1);
 return cm;
    }


}

first problem is that I can't post repeat to the cycle, and so it will not be redrawed in this content panel both with the panel I add this to.

the second problem is that this code make my app is looping

I really need help.

Thank you all.))) I've found the solution. to repeat somthing in gwt use timer.scheduleRepeating()
