AutoComplete no empty message if forceSelection is false or introduce a new attribute showEmptyMessage

Yep i was going to say that but in PF14 this will be different as we removed the EmptyMesage property as labels got moved to the client side from the server side. So in 14 this would be either

MonkeyPatch:

if (PrimeFaces.widget.AutoComplete) {
    PrimeFaces.widget.AutoComplete.prototype.configureLocale = function() {
        this.emptyMessage = '';
        this.resultsMessage = PrimeFaces.getLocaleLabel('searchMessage');
        if (this.dropdown) {
            this.dropdown.attr('aria-label', PrimeFaces.getLocaleLabel('choose'));
        }
    }
};

Or change your local to have an empty search label this.emptyMessage = PrimeFaces.getLocaleLabel('emptySearchMessage');

i think for 14.0 we need to add showEmptyMessage like PrimeReact has https://primereact.org/autocomplete/#api.AutoComplete.props.showEmptyMessage

@pizzi80 can you be a little more clear on your scenario? Maybe a reproducer showing the issue.
PrimeFaces Test

if the user is not forced to select an item from the suggested list of values
the empty message only brings confusion, for example

If you type something in the first input in the autocomple showcase,
the emptyMessage it's not what an user expect ...

I've found that if you set
emptyMessage="#{null}" or emptyMessage=""

the emptyMessage is not displayed

[pizzi80]

only as a reminder ... the emptyMessage attribute it's not documented at all

https://primefaces.github.io/primefaces/13_0_0/#/components/autocomplete?id=autocomplete

probably it's better, in this way you'll cover all the situations ;)
