PanelHow to Override this Method
There are several important things that must take place in the correct order to properly remove a Widget from a Panel. Not all of these steps will be relevant to every Panel, but all of the steps must be considered.

Widget
This method is called when a widget is attached to the browser's document.
To receive notification after a Widget has been added to the document,
override the Widget.onLoad() method or use Widget.addAttachHandler(com.google.gwt.event.logical.shared.AttachEvent.Handler).
It is strongly recommended that you override Widget.onLoad() or
Widget.doAttachChildren() instead of this method to avoid inconsistencies
between logical and physical attachment states.
Subclasses that override this method must call
super.onAttach() to ensure that the Widget has been attached
to its underlying Element.

Widget
This method is called when a widget is detached from the browser's
document. To receive notification before a Widget is removed from the
document, override the Widget.onUnload() method or use Widget.addAttachHandler(com.google.gwt.event.logical.shared.AttachEvent.Handler).
It is strongly recommended that you override Widget.onUnload() or
Widget.doDetachChildren() instead of this method to avoid inconsistencies
between logical and physical attachment states.
Subclasses that override this method must call
super.onDetach() to ensure that the Widget has been detached
from the underlying Element. Failure to do so will result in application
memory leaks due to circular references between DOM Elements and JavaScript
objects.
