Hi.
I have problem with combobox in datagrid and I doon't know what is wrong.

I use

<th data-options="field:'acPosta',width:100, 
                        formatter:function(value,row){ 
                            return row.texta; 
                        }, 
                        editor:{ 
                            type:'combobox', 
                            options:{ 
                                valueField:'ida', 
                                textField:'texta'
                            } 
                        }">Product</th>

data are [{"ida":"1","texta":"Maribor"},{"ida":"2","texta":"Kungota"},{"ida":"3","texta":"Celje"}]

I got data from
<script type="text/javascript">
    $(function(){
    $('#dg').edatagrid({
                url: '/prog/Data/Datas.phpe',
                saveUrl: '/prog/Data/DatasSave.php',
                updateUrl: '/prog/Data/DatasUpdate.php',
                destroyUrl: '/prog/Data/DatasDelete.php'
            });
        });
    </script>

everthing else work only combobox not.

thank you
