Answer 1

监听你的 itemselector 的 afterrender 事件。在回调中加载包含优先 id 的商店。

this.control({
    '#youritemselector' : {
        afterrender : this.reloadItemSelector
    }
});

...

reloadItemSelector: function(itemselector) {
    yourPriorityStore.load(function() {
        var selected = [];
        Ext.each(yourPriorityStore.data.items, function(item) {
            selected.push(item['data']['id']);
        });

        itemselector.setValue(selected);
    });
}
