Hi All,
I know, this question have been asked a thousand times, but i never found my solution.
There is it.


I have a simple Store
Code:
Ext.define('MyApp.store.Clubs', {
    extend: 'Ext.data.Store',
    alias: 'store.Clubs',




    requires: [
        'MyApp.model.Clubs'
    ],




    config: {
        groupDir: 'DESC',
        model: 'MyApp.model.Clubs',
        storeId: 'Clubs',
        proxy: {
            type: 'jsonp',
            extraParams: {
                
            },
            url: 'http://www.myurl.com/mobile/clubs.php',
            reader: {
                type: 'json',
                rootProperty: 'datas',
                totalProperty: 'totalresults'
            }
        },
        grouper: {
            groupFn: function(record) {
                return record.data.LMmember == 1 ? 'Clubs LESMILLS Members' : 'Clubs LESMILLS';
            }
        }
    }
});




 FavorisClubsStorage = Ext.create('MyApp.store.Clubs', {
        alias : 'MyApp.store.FavorisClubsStorage',
        storeId: 'FavorisClubsStorage'
    });
    FavorisClubsStorage.setAutoSync( true );
    FavorisClubsStorage.getProxy().setNoCache( true );
    FavorisClubsStorage.getProxy().setExtraParams(params);

I assign store to a dataview.List, like this :
Code:
    myDataListView.setStore("FavorisClubsStorage");
And i remove a data :
Code:
FavorisClubsStorage.remove(record);
myDataListView.refresh();
And my problem, in myDataListView, record is still here. I try to remove it in different way since few hours, but no way. Someone have an idea ?

Thanks
