> When using drop-down list you can listen to the onchange-Event (e.g. with a AjaxFormSubmitBehavior) in order to perform certain actions.
> This is not possible when using the AutocompleteTextField even if it is very like a drop-down list. Listening to onchange will activate you behavior at any keystroke and not only when the user selected one entry of the given list.
> As a "workaround" I changed the wicket-autocomplete.js in a way, that the AutocompleteTextField will fire the onload-Event whenever a selection was made. onload is no official event for a textfield in HTML so this is a kind of a hack. In addition, onload is fired when the RETURN was hit inside the textbox.
> I think the possibility to react on a selection by the user at an AutocompleteTextField would be desirable and enhances the things you can do with. E.g. I use AutocompleteTextField to display a list of matching dictionary-entries and if the user selects one of them I will load this one without additional interaction by the user. But since this is not really a very clean way of implementing this feature I'm in doubt wether this should really find it's way into a wicket release. Maybe there is already a way to listen to the mentioned event, but I didn't find it.
