How to get value from dynamically generaged editfield in Blackberry

I need to generate ui component dynamically at runtime. I am able to generate the component, but my problem is how to get value entered in dynamically generated field?

I am doing something like this.

    final HorizontalFieldManager hfm = new HorizontalFieldManager();

    for (int i=0; i<5; i++)
    {
        hfm.add(new EditField());
    }

Is there any way to set tag of field and later we could find control by tag?

As far as I know, there is no way to set a unique id for an EditField. Maybe you can use a sub class of it, and implement your own unique id mechanism. Or, as your HorizontalFieldManager holds nothing but EditField, you can get a field by position, and cast it to EditField. Like this:

Field f = hfm.getField(index);
EditField ef = (EditField)f;

UPDATE:

public class MyEditField extends EditField {

private int _id;

public MyEditField(int id) {
    _id = id;
}

public int getID() {
    return _id;
}

    //This is a cache, which holds all EditFields.

    public EditField getById(int id) {
        EditField ef = (EditField)_editfields.get(id);
        return ef;
}

    public void add(Field f) {
        super.add(f);
        if (f instanceof MyEditField) {
            _editfields.put(((MyEditField)f).getID(), f);
        }
    }

    public void delete(Field f) {
        super.delete(f);
        if (f instanceof MyEditField) {
            _editfields.remove(((MyEditField)f).getID());
        }
    }

}

And then you can do like this:

    MyHfm hfm = new MyHfm();
    hfm.add(new MyEditField(0));
    hfm.add(new MyEditField(1));
    //get the field with id
    EditField f = hfm.getById(1);

There are some other delete/add methods, remember to handle the cache inside them.
