How to load the second list in spinbox if I select/focus an item of the first list?

public class SpinTest extends BaseScreen implements FocusChangeListener {

final String[] stateList={"New York","Washington"};
final String[] NYcities={"Manhattan","Queens","Brooklyn","Bronx"} ;
final String[] WashCities={"Seattle","Redmond","Kent","Bellevue"} ;

public SpinTest(){
SpinBoxFieldManager spinBoxMgr = new SpinBoxFieldManager();

SpinBoxField spinBoxStates = new TextSpinBoxField(stateList);
spinBoxStates.setFocusListener(this);

SpinBoxField spinBoxCities= new TextSpinBoxField(NYcities);

spinBoxMgr.add(spinBoxStates );
spinBoxMgr.add(spinBoxCities);

add(spinBoxMgr);
}

public void focusChanged(Field field, int context) {
if (spinBoxStates== field) {
String sel = (String) spinBoxStates.get(spinBoxStates.getSelectedIndex() );
if (sel.equals("New York")) {

//I have to load all the cities of New York in second wheel if I select "New York" in first wheel
}
else if(sel.equals("Washington")) {
//I have to load all the cities of Washington in second wheel if I select "Washington" in first wheel
}

}

When I try with following code, it throws "IllegalArgumentException".
Please somebody help me. It's urgent.

public void focusChanged(Field field, int context) {
if (spinBoxStates== field) {
String sel = (String) spinBoxStates.get(spinBoxStates.getSelectedIndex() );
if (sel.equals("New York")) {

//I have to load all the cities of New York in second wheel if I select "New York" in first wheel

TextSpinBoxField desc = new TextSpinBoxField(NYcities);
spinBoxMgr.replace(spinBoxCities,desc);
//spinBoxCities =  new TextSpinBoxField(NYcities);
//How to refresh the manager

}
else if(sel.equals("Washington")) {

//I have to load all the cities of Washington in second wheel if I select "Washington" in first wheel

}

}

Solved !!!

public void focusChanged(Field field, int context) {
if (spinBoxStates== field) {
String sel = (String) spinBoxStates.get(spinBoxStates.getSelectedIndex() );
if (sel.equals("New York")) {
spinBoxCities.setChoices(NYcities);
}
else if(sel.equals("Washington")) {
spinBoxCities.setChoices(WashCities);
}

}
