Keep the event listener while change displayable in form

[playplay1978]

Hi.

I'm creating a form-based app where the user can navigate to next form with "Next" button and to previous form with "Back" button.

Each form basically has a few items which are clickable and have listener attached to them.

While clicking "Back" goes to displaying previous form but those events attached to those items are gone.
How can i keep those events intact?

What i do is define a Displayable object to point to that previous form

 
private Display display;
private Displayable form;
.
.
.

display = Display.getDisplay(this);
form = display.getCurrent();
.
.
.

and then, set the displayable to that previous form once "back" is clicked.

 display.setCurrent(form);

I just listed out the code snippets where it's relevant.

Please help on how to maintain the listeners for the items i mentioned above.

Thanks.

Simply attach the same listener to both Displayables. Both Forms can use the same CommandListener.

public class MyApplication extends MIDlet implements CommandListener {
    private Form form1;
    private Form form2;
    public void startApp() {
        form1 = new Form("1");
        form1.setCommandListener(this);
        form2 = new Form("2");
        form2.setCommandListener(this);
    }
    //  ... more code...
}

Thanks, Graham. It's working now!
