Hmmmm...
not quit sure if I understood you. Just for the fun of it I rehacked a
quickstart that might simulate you problem.
But even if it does I'm not quite sure if its bug, or a feature.
You add an AjaxFormComponentUpdatingBehavior to an AutoCompleteTextField.
As long as the keyboard is used to select the value or to leave the
TextField everything is fine its just that when the mouse is used to select
an element in the dropdown the AjaxFormComponentUpdatingBehavior gets called
twice.
That's not without some plausibility.
First a value is typed, so the field is changed and a dropdown is shown.
Then the mouse clicks on an element in the dropdown, the textfield looses
focus, so the first 'onchange' is fired.
Then the pulldown value is inserted into the textfield, it is changed agan
and possibly retains focus.
Finally as the mouse clicked on the dropdown, so outside of the textfield it
looses the focus again, second 'onchange' fired.
Maybe someone else has more insight, and maybe something can be done in
/wicket-autocomplete.js
