Well, the component doesn`t work like this.
The suggestedItemsMethod takes a String which was the input of the
user before the ajax-request. With the help of this string the lookup
in the db is performed and the result as
a list of strings is returned. Which exactly matches the pop-up.
If you want to get a behaviour like it can be found in menues with the
value/label approach,
you have to define a "itemLabelMethod". The suggestedItemsMethod
should then return a list of objects. The label is extracted through
the itemLabelMethod (which gets an object from the list) and the value
through a given converter.
Hope this helps,
cheers,
Gerald

But probably i can use the valueChangeListener to fetch the items
that are returned by suggestedItemsMethod?
I just tried the component with the following sniplet:
<s:inputSuggestAjax id="departures"
suggestedItemsMethod="#{createReservationController.departure.suggest.items}"
value="#{createReservationController.departure.suggest.userInput}"
valueChangeListener="#{createReservationController.departure.suggest.userInputChanged}"
maxSuggestedItems="10" size="10"
tabindex="2" />
and the following on the server side:
public void userInputChanged( ValueChangeEvent event ) {
LOG.debug( "Invoked" );
// performs a lookup in the backend
// and updates the suggested items:
suggestItems( true );
}
public Collection<SelectItem> getItems() {
return _items;
}
public String getUserInput() {
return _userInput;
}
public void setUserInput( String input ) {
_userInput = input;
}
Unfortunately, the java code is never called, even the
createReservationController.getDeparture is not called....
Can you tell me what is wrong with this?
We are using the nightly snapshot (today) of myfaces-api/impl, tomahawk
and the sandbox.
Thanx && cheers,
