Call callback inside another one

[S Roberts]

can you please suggest me, how can i call inside of first AsyncCallback after calling on Success, the second AsyncCyllback? i use gwt rpc and load my data into ui, and after calling this first AsyncCallback on Success method i must call another AsyncCallback that execute the next part of the first AsyncCallback and load data from db into ui:

void show(int last) {

    AsyncCallback<List<C>> callback = new AsyncCallback<List<C>>() {


        public void onFailure(Throwable caught) {

        }

        public void onSuccess(List<C> result) {


            panelCharts.clear();
            for (C c : result) {

                first = new Chart()
                        .setType(Series.Type.SPLINE)
                        .setSizeToMatchContainer()

                        .setLegend(
                                new Legend()
                                        .setLayout(Legend.Layout.VERTICAL)
                                        .setAlign(Legend.Align.RIGHT)
                                        .setVerticalAlign(
                                                Legend.VerticalAlign.TOP)
                                        .setX(-10).setY(100)
                                        .setBorderWidth(0))
                        .setZoomType(Chart.ZoomType.X_AND_Y);
                first.setStyleName("chart");

                Series series = first
                        .createSeries()
                        .setName("Summer")
                        .setPoints(
                                new Number[] { 7.0, 6.9, 9.5, 14.5, 18.4,
                                        21.5, 25.2, 26.5, 23.3, 18.3, 13.9,
                                        9.6 });
                first.setCredits(new Credits().setEnabled(false));
                first.addSeries(series);

                first.setChartTitleText(c.getName());



                AsyncCallback<List<M>> callbackA = new AsyncCallback<List<M>>() {
                    public void onFailure(Throwable caught) {

                    }

                    public void onSuccess(List<M> result) {


                        for (M m : result) {
                            Series serie = firstChart.createSeries().setName(
                                    m.getDName());

                            first.addSeries(serie);
                     }

                    }


                };

                rpcService.getKList(ID, callbackA);
                panelCharts.add(first);
            }
            }


    };
    rpcService.getList(last, callback);

i get no exceptions, that second asynccallback doesnt work, cant load the data

[Joanne Neal]

This appears to be the same question as you asked here

[S Roberts]

yes, i did it like in sample that i posted, and the first asynccallback is work and i can get the data from db, but the second asynccallback doesn't do anything
