Collection of Collections of datetimepickers not being populated

[Tony Schlemmer]

This is first post on the Java Ranch.

I am using struts 2.0.14 and I'm having an issue where I have a Collection of Collections of datetimepicker values. I am retrieving the time values from a database and they are all being displayed properly. I can make changes to the time and it is working. The problem that I have is when I submit the page back the Collections are empty within the Java code when the update() method is called.

The list is returned from another class:

Here is the code that populates the Collection:

public Collection<WindowBean> getMainList()
{
	return mainList;
}

Here is my WindowBean Java code (fairly simple):

public class WindowBean 
{
	private static Hashtable<String,String> hash = new Hashtable<String,String>();
	private String day;
	private String location;
	private String weekday;
	private String starttimehr;
	private String starttimemn;
	private String endtimemn;
	private String endtimehr;
	private String desc;
	private String starttime;
	private String endtime;
		
	private static boolean init = false;
	
	public WindowBean(String location, String day, String starthr, String startmn,
			String endhr, String endmn, String desc)
	{
		if (!init)
		{
			initialize();
			init = true;
		}
				
		this.location = location;
		this.day = day;
		this.weekday = (String)hash.get(day.trim());
		this.starttimehr = starthr;
		this.starttimemn = startmn;
		this.endtimehr = endhr;
		this.endtimemn = endmn;
		this.desc = desc;
				
		// Set start time
		this.starttime=this.starttimehr+":"+this.starttimemn;
		
		// set end time
		this.endtime=this.endtimehr+":"+this.endtimemn;

	}
	
	public synchronized void initialize()
	{
		hash.put("Sun", "Sunday");
		hash.put("Mon", "Monday");
		hash.put("Tue", "Tuesday");
		hash.put("Wed", "Wednesday");
		hash.put("Thu", "Thursday");
		hash.put("Fri", "Friday");
		hash.put("Sat", "Saturday");
	}
	
	public void setLocation(String location)
	{
		this.location = location;
	}
	
	public String getLocation()
	{
		return this.location;
	}
	
	public void setDay(String day)
	{
		this.day = day;
	}
	
	public String getDay()
	{
		return this.day;
	}
	
	public void setWeekday(String day)
	{
		this.weekday = day;
	}
	
	public String getWeekday()
	{
		return this.weekday;
	}
	
	public String getDesc()
	{
		return this.desc;
	}
	
	public void setDesc(String desc)
	{
		this.desc = desc;
	}
	
	public String getStarttime()
	{
		return this.starttime;
	}
	
	public String getEndtime()
	{
		return this.endtime;
	}
	
	public void setStarttime(String time)
	{
		this.starttime = time;
	}

	public void setEndtime(String time)
	{
		this.endtime = time;
	}
		
	public String getStarttimehr()
	{
		return this.starttimehr;
	}
	
	public void setStarttimehr(String start)
	{
		this.starttimehr = start;
	}
	
	public String getStarttimemn()
	{
		return this.starttimemn;
	}
	
	public void setStarttimemn(String start)
	{
		this.starttimemn = start;
	}
	
	public String getEndtimehr()
	{
		return this.endtimehr;
	}
	
	public void setEndtimehr(String end)
	{
		this.endtimehr = end;
	}
	
	public String getEndtimemn()
	{
		return this.endtimemn;
	}
	
	public void setEndtimemn(String end)
	{
		this.endtimemn = end;
	}
}

Thank for any help you can give me.
