I've just tried it myself in the playground and the FocusHandler returned me
the current focused widget (in the case of the code below this has to be the
button).

The problem here is that the focussing is done asynchron inside the qooxdoo
element queue.
If you change your event listener code to
--snip--
bt1.addListener("execute",function() {
var self = this;
this.__field.focus();
qx.event.Timer.once(function() {
var focusedWidget =
qx.ui.core.FocusHandler.getInstance().getFocusedWidget();
this.__field.setValue(focusedWidget + "");
}, self, 0);
},this);
--snip--
it should work.
cheers,
Alex
