Errors in development mode for List Grid.

[mehul_lucky4u]

Hi,

When I use check box, frozen first column and roll over canvas together in list grid then I am getting following errors in development mode.

I am using following browsers - FF 11 & 17 and IE 8.
SmartClient Version: v8.3d_2012-11-19/LGPL Development Only



Here is the sample code:-

package org.yournamehere.client;
import com.google.gwt.core.client.EntryPoint;
import com.smartgwt.client.types.*;
import com.smartgwt.client.widgets.Canvas;
import com.smartgwt.client.widgets.grid.ListGrid;
import com.smartgwt.client.widgets.grid.ListGridField;
import com.smartgwt.client.widgets.grid.ListGridRecord;
import com.smartgwt.client.widgets.layout.HLayout;
public class MainEntryPoint implements EntryPoint {
    private HLayout rollOverCanvas;
    private ListGridField continentField = new ListGridField("continent", "continent", 200);
    private ListGridField countryNameField = new ListGridField("countryName", "countryName", 150);
    private final ListGrid countryGrid = new ListGrid() {
        @Override
        protected Canvas getRollOverCanvas(Integer rowNum, Integer colNum) {
            return rollOverCanvas;
        }
    };
    public void onModuleLoad() {
        rollOverCanvas = new HLayout();
        rollOverCanvas.setSnapTo("TR");
        rollOverCanvas.setWidth(40);
        rollOverCanvas.setHeight(22);
        rollOverCanvas.setBackgroundColor("red");
        //removing any of these 3 lines causes no errors in dev mode
        continentField.setFrozen(true);
        countryGrid.setShowRollOverCanvas(true);
        countryGrid.setSelectionAppearance(SelectionAppearance.CHECKBOX);
        
        countryGrid.setWidth(500);
        countryGrid.setHeight(400);
        countryGrid.setFields(continentField, countryNameField);
        countryGrid.setData(getData());
        countryGrid.draw();
    }
    private CountryRecord[] getData() {
        return new CountryRecord[]{
                    new CountryRecord("North America", "United States"),
                    new CountryRecord("Asia", "China"),
                    new CountryRecord("Asia", "Japan"),
                    new CountryRecord("Asia", "India"),
                    new CountryRecord("Europe", "Germany"),
                    new CountryRecord("Europe", "United Kingdom"),
                    new CountryRecord("Europe", "France")};
    }
    private class CountryRecord extends ListGridRecord {
        public CountryRecord(String continent, String countryName) {
            setAttribute("continent", continent);
            setAttribute("countryName", countryName);
        }
    }
}

Thanks in advance!

This was already fixed on 21 November, two days after the version you're using. You just need to update to the latest patch build - you should always try this if you hit bugs, in case they've already been addressed.
