    Unanswered: Error while using convert in Model


    hi I'm trying to use convert config of field
    but get this error
    TypeError: 'undefined' is not an object (evaluating 'record.retailer.name')

    this is my model

    Code:
    function retailerDetail(v, record){
        return record.retailer.name + ', ' + record.retailer.retailerID+','+record.retailer.URL;
    }
    function locationDetail(v,record)
    {
        return record.location.line1+','+record.location.line2+','+record.location.city+','+record.location.postcode;
        
    }
    function vatDetail(v,record)
    {
        return record.vat.rate+','+record.vat.net+','+record.vat.vat+','+record.vat.gross;
    }
    Ext.regModel('receipts_model', {
        fields:[
        {name:'timestamp',type:'auto'},
        {name:'receiptID',type:'auto'},
        {name:'Identifier',type:'auto'},
        {name:'retailer',convert:retailerDetail},
        {name:'name',mapping:'retailer.name'},
        {name:'retailerID',mapping:'retailer.retailerID'},
        {name:'URL',mapping:'retailer.URL'},
        {name:'transactionID',type:'auto'},
        {name:'postcode',type:'auto'},
        {name:'location',convert:locationDetail},
        {name:'line1',mapping:'location.line1'},
        {name:'line2',mappimg:'location.line2'},
        {name:'city',mapping:'location.city'},
