Andrea Del Bene commented on WICKET-5603:
-----------------------------------------
Why not checking for the type of component inside updateAjaxAttributes? we
could use event 'inputchange' for TextArea and TextField, while event 'change'
will be used for any other component.
> OnChangeAjaxBehavior attached to DropDownChoice produces two Ajax requests in
> Chrome v35
