Exception PageProxy in gridpanel row expander

[78fede78]

if you build the store on the page init, compilation is ok.

  protected void Page_Init(object sender, EventArgs e)    
    { 
        storepoi = new Store { ID = "StoreRow" };
        Ext.Net.PageProxy gh = new Ext.Net.PageProxy();
        gh.Total = WAY.Business.BusinessTarget.GetCountTargets(-1,1);        
        storepoi.Proxy.Add(gh);
        JsonReader reader = new JsonReader(); 
        reader.IDProperty = "ID";
        reader.Fields.Add("ID", "Name");        
        storepoi.Reader.Add(reader);        
        List<object> data = new List<object>();       
        ///storepoi.RefreshData += new Store.AjaxRefreshDataEventHandler(Store1_RefreshData);
        storepoi.DataSource = WAY.Business.BusinessTarget.GetTargetsList(-1, 1, 8, 0);
        this.Form.Controls.Add(storepoi); 
        //important
    }

but the behavior is wrong!!

grids daughters share the same store and this is not good.

Hello!

Could you provide me with a small example demonstrating the wrong behavior?
