how to refresh a list using a data store with the ajax proxy without new

[dhagan]

Hi Folks,
I'm cloning the kiva LoanList example and I'm able to load the list from using an Ajax proxy. The rub is that if I want to reload with a new URL, the only way I can figure out to do it is with a new data data store, ie this.store = new Ext.data.store() etc. Unless I'm missing something, I'm not seeing the load() or reload(). I see older references to reload(params{}) but I can't get them to work. Any pointers? Snippet below:

  filterResults: function (filterBar, values) {
        //alert("DJH reload offer list here");

        function doReefresh(request, success) {
            if (success) {
                this.refresh();
            } else {
                alert("Search request failed");
            }
        }

        this.store = new Ext.data.Store({
            model: 'Offer',
            sorters: [{
                field: 'title'
            }],
            proxy: {
                type: 'ajax',
                //url: getSearchURL(),
                url: 'http://localhost/php/sencha/examples/digisearch/list1.json',
                //url: 'http://dev.jugger.com/digipowers/phone/digisearch/list.json',
                //url: '/list.json',
                reader: {
                    type: 'json',
                    root: 'offers'
                },
                // DJH question, why is this.refresh() not in scope?
                //afterRequest: doRefresh(request, success)
                
                afterRequest: function (request, success) {
                    if (success) {
                        // this.refresh() is not in scope?
                        //this.refresh();
                    } else {
                        alert("Search request failed");
                    }
                } 

            },
            autoLoad: true,
            listeners: {
                scope: this,
                datachanged: function () {
                    alert('4');
                    //DJH this refresh is accessible this.refresh();
                }
            }
        });

        // DJH, this is worthwhile, but being called to early.
        this.refresh();

        //        //
        //        // DJH this doesn't work
        //        //
        //        // http://tdg-i.com/325/ext-js-screencast-data-stores-and-gridpanels
        //        this.store.proxy.api.read.url = 'http://localhost/php/sencha/examples//list1.json'
        //        this.store.reload();
        //        // DJH Neither does this
        //        this.store.reload({
        //            model: 'Offer',
        //            sorters: [{
        //                field: 'title'
        //            }],
        //            proxy: {
        //                type: 'ajax',
        //                url: 'http://localhost/php/sencha/examples/list1.json',
        //                reader: {
        //                    type: 'json',
        //                    root: 'offers'
        //                }
        //            },
        //            listeners: {
        //                scope: this,
        //                datachanged: function () {
        //                    alert('4');
        //                }
        //            }
        //        }
        //        );


    }
