Okay, I've got this thing just about done, but getModelObject() is final in Component. How do I take the inputs from three separate DropDownChoices and return a Time object if not through getModelObject()?
And if I use another method, will Page's model object automatically be updated with the appropriate Time value?
Thanks for your help. Here's the non-compiling code that I have so far:
import wicket.MarkupContainer;
import wicket.markup.html.form.DropDownChoice;
import wicket.model.Model;
import java.sql.Time;
import java.util.Arrays;
import java.util.List;
import java.util.Calendar;
import java.util.GregorianCalendar;
public class TimeSelector extends MarkupContainer {
private static final List<String> hourList =
Arrays.asList(new String[]{"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12"});
private static final List<String> minuteList =
Arrays.asList(new String[]{"00", "05", "10", "15", "20", "25", "30", "35", "40", "45", "50", "55"});
private static final List<String> amPmList =
Arrays.asList(new String[]{"AM", "PM"});
private DropDownChoice hours;
private DropDownChoice minutes;
private DropDownChoice amPm;
private Calendar c = Calendar.getInstance();
public TimeSelector(final String id, Model m) {
super(id, m);
Time t = (Time) getModelObject();
Model hourModel = new Model(getValueFromModel(t, Calendar.HOUR));
hours = new DropDownChoice("hour", hourModel, hourList);
add(hours);
Model minuteModel = new Model(getValueFromModel(t, Calendar.MINUTE));
minutes = new DropDownChoice("minute", minuteModel, minuteList);
add(minutes);
Model amPmModel = new Model(getValueFromModel(t, Calendar.AM_PM));
amPm = new DropDownChoice("amPm", amPmModel, amPmList);
add(amPm);
}
public TimeSelector(final String id, Time t) {
this(id, new Model(t));
}
private String getValueFromModel(Time t, int component) {
c.setTime(t);
switch (component) {
case Calendar.HOUR:
return Integer.toString(c.get(Calendar.HOUR));
case Calendar.MINUTE:
return Integer.toString(c.get(Calendar.MINUTE));
default:
return (c.get(Calendar.AM_PM) == Calendar.AM) ? "AM" : "PM";
}
}
public Object getModelObject() {
GregorianCalendar gc = new GregorianCalendar();
String hourValue = hours.getModelObjectAsString();
String minuteValue = minutes.getModelObjectAsString();
String amPmValue = amPm.getModelObjectAsString();
gc.set(Calendar.HOUR, Integer.parseInt(hourValue));
gc.set(Calendar.MINUTE, Integer.parseInt(minuteValue));
if (amPmValue.equals("AM")) {
gc.set(Calendar.AM_PM, Calendar.AM);
}
else {
gc.set(Calendar.AM_PM, Calendar.PM);
}
return new Time(gc.getTime().getTime());
}
}

I need to build a simple drop-down time component that allows the user to select an hour, minute (in 5-minute increments) and AM/PM. Ideally, the calling code would look something like:
TimeSelector ts = new TimeSelector("myModelName", myModelObject);
add(ts);
So the TimeSelector class would have three DropDownChoices. What actually returns the selected Time? getModelObject()?
