Invoking navigationClick from navigationClick 'father' in Blackberry - blackberry

Question

Edited
...
I´m trying to deploy a new component in my BlackBerry app. I have a new class that extends of HorizontalFieldManager, where I instanced a new ListField. Inside of this, I overwrote the navigationClick method and I open a popup. The name of this component is CustomComponentHorizontal. I use this component in other component customized, its name is CustomComponentVertical. This is the code:
In Main.java:
...
CustomComponentVertical ccv=new CustomComponentVertical();
...
add(ccv);
In CustomComponentVertical
...
CustomComponentHorizontal cch=new CustomComponentHorizontal{
...
protected boolean navigationClick(int status, int time) {
//Should I do something here??
return super.navigationClick(status, time);
}
};
...
add(cch);
In CustomComponentHorizontal:
public class CustomComponentHorizontal extends HorizontalFieldManager {
ListField choiceField=null;
PopupScreen popup=null;
public CustomComponentHorizontal (){
choiceField = new ListField(){
public boolean navigationClick(int status, int time) {
Field focus = UiApplication.getUiApplication().getActiveScreen().getLeafFieldWithFocus();
if (focus instanceof ListField) {
popup = new ChoicePopupScreen(10, 50, choices);
popup.setChoice(choices);
UiApplication.getUiApplication().pushScreen(popup);
setPopup(popup);
return super.navigationClick(status, time);
}
};
}
}
}
My purpose is that when I click in my component, it is launched the navigationClick of listfield. When I put the focus in my component and click with trackpad, the popup no open. But, If I touch the screen over the component, and then I click with trackpad, popup open.
How could I open the popup from component without to use the touch event?
Thank you very much.

I copy pasted your code. There were some errors, and your callback was missing. So I fixed it up a bit and created a simple callback to test with, and the navigationClick fires. Hopefully this helps, let me know if there is a different issue I didn't understand.
public CustomComponent()
{
elements = new Vector();
elements.addElement("Element 0");
elements.addElement("Element 1");
elements.addElement("Element 2");
elements.addElement("Element 3");
elements.addElement("Element 4");
elements.addElement("Element 5");
choiceField = new ListField(elements.size())
{
public boolean navigationClick(int status, int time)
{
int index = getSelectedIndex();
Dialog.inform((String) elements.elementAt(index));
return true;
}
};
choiceField.setCallback(new ListFieldCallback()
{
public int indexOfList(ListField listField, String prefix, int start)
{
return elements.indexOf(prefix, start);
}
public int getPreferredWidth(ListField listField)
{
return Display.getWidth();
}
public Object get(ListField listField, int index)
{
return elements.elementAt(index);
}
public void drawListRow(ListField listField, Graphics graphics, int index, int y, int width)
{
String obj = (String) get(listField, index);
graphics.setColor(0x000000);
graphics.drawText(obj, 0, y, 0, width);
}
});
add(choiceField);
}
