added and the infoWindow is shown. when i click on the info window, i get
the below error.

gmap.addControl(GControl.GMapTypeControl);
gmap.addControl(GControl.GLargeMapControl);
gmap.setOutputMarkupId(true);
gmap.setScrollWheelZoomEnabled(true);
gmap.add(new ClickListener() {
@Override
protected void onClick(AjaxRequestTarget target, GLatLng glatLng,
GOverlay overlay) {
// GMarkerOptions gmo = new GMarkerOptions();
// gmo.draggable(true);
// gmo.bouncy(true);
if (!(overlay instanceof GMarker)) { //This section was added
to stop the same error from occouring when the marker is clicked.
GMarker gm = new GMarker(glatLng);
gmap.getInfoWindow().open(glatLng,
new Label("Hello", "Hi , am here"));
gmap.addOverlay(gm);
}
}
});
add(gmap);
}
}
