Hi, I have a problem. In my application I am trying to do that when I click a button on my screen load certain values in a LabelField​​. I've tried to do with the FocusChangedListener, but these changes only occur when changing the focus, is there anything that changes occur when I press the button? sorry for my poor English

I've tried FielChangeListener and does not work, this is my code:

...

ayudaButton = new BitmapButtonField(iconoPlayFocus, iconoPlayUnfocus);

//      ayudaButton.setFocusListener(this);
        ayudaButton.setChangeListener(this);

.....

public void fieldChanged(Field field, int eventType) {
        
        if(field != ayudaButton){
               return;
        }
        
        clienteInput.setText(controller.getClienteActual().getId());
        nombreInput.setText(controller.getClienteActual().getNombre());

}

you have to trigger the fieldchanged event manually most likly, as the BitmapButtonField class does not do it.
classic approach is to overwrite keyChar(enter key) and navigationclick.

If you are using the BitmapButtonField class from RIM Advanced UI Samples, then you would use this:

ayudaButton = new BitmapButtonField(iconoPlayFocus, iconoPlayUnfocus){
public void clickButton() {
clienteInput.setText(controller.getClienteActual().getId());
nombreInput.setText(controller.getClienteActual().getNombre());
}
};

The problem is that in the initial screen, there is a object with anythingvalues ​​and if you click on the BitmatButtonField, we go to another screen and updates the value of the object, and I want to do this, regenerate or paint it screen again with updated data object, is it possible??

Finally I added an element in a common class to all screens (class controller) to solve.
