Sencha Touch: Reload NestedList and TreeStore after proxy URL change

I have and application that uses NestedList with a TreeStore. TreeStore is using AJAX type proxy and XML reader. Now I have implemented Settings page, where you can change the URL that is used as a data source. Application needs to "reload" after that change. As a result, I change proxy URL:

App.tree_store.proxy.url = new_url;

Then I would like to load a new data:

App.tree_store.load();

When I switch NestedList to root card, it will contain mixed data from previous configuration and current one:

App.views.hdTreeView.setActiveItem(0);

Question: How should I "clear/reset" NestedList before loading entirely new data (same data model)? Do I have to clear TreeStore / SubStores and Proxy as well, if yes, how? Maybe using destroy() method and recreate new components?

If I remove all lists using removeAll() and than reload store, new list will not be created.

Thanks!

 showDetail: function(list, index , element , record) {
            //Take your store
            var store = Ext.getStore('yourstore');

            //Apply the params
            Ext.apply(store.getProxy()._extraParams, {
                id : record.data.id
            });

            //Reload your store
            store.load();
}

put this code at controller

just change extraParams to fetch new data.

in store dont input exterparam.

so u cab use just one url but chnage just param for fetch data.

First use store.setProxy() and pass new proxy object then use this:

nestedListObject.bindStore(store.load());

where the nestedListObject is your nested list.
