Random cell selection at start

[sipungora]

Hi,

it is a matter of cell selection in grid.

After data arrived I select programmatically some cell. If I start to navigate with arrow keys -> or <- the first time it jump to a some random cell. After that one can navigate as one expects.

How can I solve it?

I adapted some class from Showcase:

package com.smartgwt.sample.showcase.client.grid.editing;

import com.google.gwt.i18n.client.NumberFormat;
import com.smartgwt.client.types.Alignment;
import com.smartgwt.client.types.ListGridEditEvent;
import com.smartgwt.client.types.ListGridFieldType;
import com.smartgwt.client.types.SelectionStyle;
import com.smartgwt.client.types.SortArrow;
import com.smartgwt.client.widgets.Canvas;
import com.smartgwt.client.widgets.events.KeyDownEvent;
import com.smartgwt.client.widgets.events.KeyDownHandler;
import com.smartgwt.client.widgets.grid.CellFormatter;
import com.smartgwt.client.widgets.grid.ListGrid;
import com.smartgwt.client.widgets.grid.ListGridField;
import com.smartgwt.client.widgets.grid.ListGridRecord;
import com.smartgwt.sample.showcase.client.PanelFactory;
import com.smartgwt.sample.showcase.client.ShowcasePanel;
import com.smartgwt.sample.showcase.client.data.CountryXmlDS;

public class GridEditByCellSample extends ShowcasePanel {
    private static final String DESCRIPTION =
        "<p><b>Click</b> on any cell to start editing. Use <b>Tab</b>, <b>Shift-Tab</b>,"
            + "<b>Up Arrow</b>, and <b>Down Arrow</b> to move between cells.</p><p>Press <b>Enter</b> to save the current row"
            + "and dismiss the editors, or <b>Esc</b> to discard changes for the current cell and dismiss"
            + "the editors.</p>";

    public static class Factory implements PanelFactory {
        private String id;

        public Canvas create() {
            GridEditByCellSample panel = new GridEditByCellSample();
            id = panel.getID();
            return panel;
        }

        public String getID() {
            return id;
        }

        public String getDescription() {
            return DESCRIPTION;
        }
    }

    public Canvas getViewPanel() {

        final ListGrid countryGrid = new ListGrid();
        countryGrid.setWidth(550);
        countryGrid.setHeight(224);
        countryGrid.setShowAllRecords(true);
        countryGrid.setCellHeight(22);

        // use server-side dataSource so edits are retained across page transitions
        countryGrid.setDataSource(CountryXmlDS.getInstance());

        ListGridField countryCodeField = new ListGridField("countryCode", "Flag", 40);
        countryCodeField.setAlign(Alignment.CENTER);
        countryCodeField.setType(ListGridFieldType.IMAGE);
        countryCodeField.setImageURLPrefix("flags/16/");
        countryCodeField.setImageURLSuffix(".png");
        countryCodeField.setCanEdit(false);

        ListGridField nameField = new ListGridField("countryName", "Country");
        ListGridField continentField = new ListGridField("continent", "Continent");
        ListGridField memberG8Field = new ListGridField("member_g8", "Member G8");
        ListGridField populationField = new ListGridField("population", "Population");
        populationField.setType(ListGridFieldType.INTEGER);
        populationField.setCellFormatter(new CellFormatter() {
                public String format(final Object value, final ListGridRecord record, final int rowNum,
                        final int colNum) {
                    if (value == null) {
                        return null;
                    }

                    try {
                        NumberFormat nf = NumberFormat.getFormat("0,000");
                        return nf.format(((Number) value).longValue());
                    } catch (Exception e) {
                        return value.toString();
                    }
                }
            });

        ListGridField independenceField = new ListGridField("independence", "Independence");
countryGrid.setFields(countryCodeField, nameField, continentField, memberG8Field, populationField, independenceField);

        countryGrid.setAutoFetchData(true);

        countryGrid.setSelectionType(SelectionStyle.MULTIPLE);
        countryGrid.setCanDragSelect(true);
        countryGrid.setCanSelectCells(true);

        grid.addDataArrivedHandler(new DataArrivedHandler() {

                @Override
                public void onDataArrived(final DataArrivedEvent event) {
                    RecordList recordList = grid.getRecordList();
                    if (recordList != null) {

                        CellSelection cellSelection = grid.getCellSelection();
                        if (cellSelection != null) {
                            cellSelection.selectCell(3, 1);
                        }
                    }
                }

            });
        return countryGrid;
    }

    public String getIntro() {
        return DESCRIPTION;
    }

}

Thank you in advance,
