I have a MainScreen in which I am adding my LocationPicker. I call add(locationPicker);

I call this method before, to set up the locationPicker.

private void readyLocationPicker(){
	Vector locationpick = new Vector();
	

	locationpick.addElement(GPSLocationPicker.getInstance());

	
	Landmark[] landmarks = new Landmark[1];
	landmarks[0] = new Landmark("DC Beltway", "Center of 495 Beltway", new QualifiedCoordinates(LATITUDE_CENTER_OF_DC_BELTWAY, LONGITUDE_CENTER_OF_DC_BELTWAY, Float.NaN, Float.NaN, Float.NaN), null);
	final SuggestedLocationPicker slp = SuggestedLocationPicker.getInstance("Suggested Locations...", landmarks);
	locationpick.addElement(slp);
	
	locationpick.addElement(EnterLocationPicker.getInstance(true));
	locationpick.addElement(MapsLocationPicker.getInstance());
	locationpick.addElement(RecentLocationPicker.getInstance());
	locationpick.addElement(ContactsLocationPicker.getInstance(true));

	LocationPicker.Picker[] locationPickersArray = new LocationPicker.Picker[locationpick.size()];
	locationpick.copyInto(locationPickersArray);

	locationPicker = LocationPicker.getInstance(locationPickersArray);
	locationPickListener = new LocationPicker.Listener() {
		
		public void locationPicked(Picker picker, Landmark location) {
			if(picker==slp){
				//TODO: Change radius field to 30 Miles
				choiceRadius.setSelectedValue(30);
			}
			System.out.println("Landmark: " + location);
		}
	};
	locationPicker.setListener(locationPickListener);
}

I have no idea what is going on, and why it won't work.

Thanks.

I can't figure this out, does anyone have a clue as to what may be causing this?

From where are you calling readyLocationPicker?

[weaselgrater]

        public AdvancedIncidentListOptions()
        {
        	readyComponents();
        	addComponents();
        }

The constructor for a subclass of MainScreen,

private void readyComponents(){
	readyLocationPicker();
	
	choiceRadius = new NumericChoiceField("Radius(mi):", 5, 50, 5, 2);

	timeNumber = new NumericChoiceField("", 1, 20, 1, 0){
		
		public void layout(int width, int height){
            super.layout(width,height);
            setExtent((getWidth()/5),20);       
        }

	};

.....
}

Then adding it screwed everything up:

private void addComponents(){
	LabelField lblLocation = new LabelField("Location:");
	lblLocation.setFont(Font.getDefault().derive(Font.BOLD, Font.getDefault().getHeight() + 2));
	add(new LabelField("Location:"));
	//PROBLEM: add(locationPicker);
	add(choiceRadius);

Where else could I put this so that it works, (if that is the problem)? Is this a general error that someone understands?

 Oh, it extends Screen. Silly me. Here's how I got it to work:

locationPickerButton = new ButtonField("Location", ButtonField.CONSUME_CLICK | ButtonField.FIELD_RIGHT);
locationPickerButton.setChangeListener(new FieldChangeListener() {
	public void fieldChanged(Field field, int context) {
		
		locationPicker.show();
        locationPickerButton.setLabel(locationPickerLocation.getName());
  
	}
});
