                />

Answer 1

If you prefer json autocompleter to list one you can do :

define the onSelectTopics of the first on to a specific value like

onSelectTopics="/mapNameListChange"

define for the second

listenTopics="/mapNameListChange"

create a function like :

$.subscribe("/mapNameListChange",function(event, data){
            //clear the children autocompleters
            jQuery('#mapTypeList').val("");
            jQuery('#mapTypeList_widget').val("");
            var ui = event.originalEvent.ui;
            if (ui.item && ui.item.value.length > 0) {
                setJQueryAutocompleterURL(jQuery('#mapTypeList_widget'),"your json request", "extraparameter=" + ui.item.value, "the list used in the json", "mapTypeList", "map_type", "/mapNameListChange", "/mapTypeListChange");
            };
        },null);

where setJQueryAutocompleterURL is another function

function setJQueryAutocompleterURL(widget,href, hrefparameter, list, id, name, selectTopics, listenTopics) {

        var options_auto_iban_widget = {};
        options_auto_iban_widget.hiddenid = "mapTypeList";
        options_auto_iban_widget.selectBox = true;
            options_auto_iban_widget.selectBoxIcon= true;
        options_auto_iban_widget.forceValidOption = true;
        options_auto_iban_widget.onselecttopics = "/autoDebtorIbanChange";
        options_auto_iban_widget.list = list;
        options_auto_iban_widget.listkey = "id";
        options_auto_iban_widget.listvalue = "name";
        options_auto_iban_widget.jqueryaction = "autocompleter";
        options_auto_iban_widget.id = id;
        options_auto_iban_widget.name = name + "_widget";
        options_auto_iban_widget.href = href+"?"+hrefparameter;
        options_auto_iban_widget.listentopics = "/autoDebtorBicChange"; 
        jQuery.struts2_jquery_ui.bind(widget,options_auto_iban_widget);
    }

Then you will have the extraparameter to get as a param of your json call to filter the result.
