Code:
[IMG]file:///D:/Users/Fahd/AppData/Local/Temp/moz-screenshot.png[/IMG][IMG]file:///D:/Users/Fahd/AppData/Local/Temp/moz-screenshot-1.png[/IMG]Rpt.JsonStore = function(){   
    Rpt.JsonStore.superclass.constructor.call(this, {
       id: 'ReportDataStore',
        remoteSort: true,
        sortInfo: {field: 'Cin', direction: 'DESC'}
    });
};

Ext.extend(Rpt.JsonStore, Ext.data.JsonStore, {
    SetProxy: function(proxy){
        this.proxy = proxy;
    },
    
    SetReader: function(reader){
        this.reader = reader;
    },
       
    LoadReport: function(SP, ContainerJSON){
        this.load(
                { params: { SPName: SP, Parameters: ContainerJSON }}
            );
    },
    GetStore: function(){
        return this.GetStore();
    }
});
How do I inherit recordType()?

Thanks
