MouseEvent does not inherit data

I have a custom button component with the following doClick_ in my javascript:

doClick_: function (evt) {
    evt.data.enterKeyPressed = this._enterKeyPressed;
    this._enterKeyPressed = false;
    this.$supers('doClick_', arguments);
},

In the java code of my widget in the service method:

public void service(org.zkoss.zk.au.AuRequest request, boolean everError) {
    final String cmd = request.getCommand();
    if (cmd.equals(Events.ON_CLICK)) {
        Event evt = Event.getEvent(request);
        MouseEvent mevt = MouseEvent.getMouseEvent(request);

The evt variable contains the enterKeyPressed in data, however if I create a MouseEvent the mevt variable has _data of null. It seems the MouseEvent.getMouseEvent(request) strips the data.

Is there a work around for this ? I need to fire a MouseEvent with the data I added on the javascript side.

Thanks.
