command listener problems in MIDP

I am trying to get my Form to react on incoming commands but my commandlistener doesnt work.

I extend the class Form and implements the commandListener interface, like this

public class ReportForm extends Form implements CommandListener{

...

}

I implement the commandAction method like

public void commandAction(Command c,Displayable s){

append("hello!");

}

and in my constructor i set the commandListener :

setCommandListener(this);

But it seems that when I press a button the commandAction() method isn't called. Is there something else i should do to get it to work?
