Class AutoCompleteTextBoxAsync

java.lang.Object
  extended by com.google.gwt.user.client.ui.UIObject
      extended by com.google.gwt.user.client.ui.Widget
          extended by com.google.gwt.user.client.ui.FocusWidget
              extended by com.google.gwt.user.client.ui.TextBoxBase
                  extended by com.google.gwt.user.client.ui.TextBox
                      extended by org.drools.brms.client.common.AutoCompleteTextBoxAsync
All Implemented Interfaces:
com.google.gwt.user.client.EventListener, com.google.gwt.user.client.ui.HasFocus, com.google.gwt.user.client.ui.HasName, com.google.gwt.user.client.ui.HasText, com.google.gwt.user.client.ui.KeyboardListener, com.google.gwt.user.client.ui.SourcesChangeEvents, com.google.gwt.user.client.ui.SourcesClickEvents, com.google.gwt.user.client.ui.SourcesFocusEvents, com.google.gwt.user.client.ui.SourcesKeyboardEvents
public class AutoCompleteTextBoxAsync
extends com.google.gwt.user.client.ui.TextBox
implements com.google.gwt.user.client.ui.KeyboardListener

This nifty utility provides auto completion. Drop in replacement for a text box. I recall lifting it from somewhere on http://del.icio.us/michaelneale/GWT, plus some small tweaks. If this gives any back chat, I will shut it down and we can just use a regular text box.
