Test case is as follows:

package pl.com.tech4.client;

import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.datepicker.client.CalendarUtil;
import com.smartgwt.client.data.Record;
import com.smartgwt.client.util.SC;
import com.smartgwt.client.widgets.calendar.Calendar;
import java.util.Date;

public class MainEntryPoint implements EntryPoint {

    public void onModuleLoad() {

        layout();
        SC.showConsole();
    }

    private void layout() {

        Calendar calendar = new Calendar();
        calendar.setStartDateField("startTime");
        calendar.setEndDateField("endTime");
        calendar.setShowDayView(true);
        calendar.setShowWeekView(false);
        calendar.setShowMonthView(false);
        calendar.setShowWorkday(true);

        Record[] data = new Record[1];
        data[0] = new Record();
        data[0].setAttribute("name", "test");
        data[0].setAttribute("title", "Test");
        Date yesterday = new Date();
        CalendarUtil.addDaysToDate(yesterday, -1);
        data[0].setAttribute("startTime", yesterday);
        Date tomorrow = new Date();
        CalendarUtil.addDaysToDate(tomorrow, 1);
        data[0].setAttribute("endTime", tomorrow);

        calendar.setData(data);

        calendar.draw();
    }

}

Thanks,
