If there is only a single suggestion, I would like to fire "onSelect". The reason : beside normal text, I also can receive (long) barcodes on the field. If this is the case, I don't need the extra interaction from the user.
autoSelectFirst : will select the first field but an enter is still required; (which is confusing since it might fire the entire form)

I tried with onSearchComplete, since this is a ajax call. But I can't (or don't know how) to fire onSelect function.

$('#autocomplete').autocomplete({	serviceUrl: 'get_product',	onSelect: function (suggestion) {	console.log("onselect shot");	var res = suggestion.data;	$("#pid").val(res.id);	// some more code	},	onSearchComplete: function (query, suggestion) {	if(suggestion.length == 1 && query.length > 20)	{	this.OnSelect(0); // this is invalid	}	},	autoSelectFirst: true,	minChars: '2' }); 

I also tried with onHint, but then I have no idea when there is only 1 result. If I missed the obvious, sorry ! Thanks for this wonderful library !
