jQuery Grid Plugin - jqGrid

Hi,

I finally managed to view a record of my grid using a custom dialog.

This is what I do:

--------------------------------------------------------------------------------------------------------------------------------------------

                    var ret = jQuery("#griglia-negozi").jqGrid('getRowData', idbut);

                    var $dialog = $('<div></div>')

                    // Testo della finestra
                    .html('<form name="order" id="order" > '+
                          ' <fieldset> '+
                          '     <legend>Invoice Data</legend> '+
                          '     <table> '+
                          '         <tbody> '+
                          '             <tr> '+
                          '                 <td> Nome Negozio:</td> '+
                          '                 <td><input type="text" name="nomenegozio" readonly=true id="nomenegozio"/></td> '+
                          '             </tr> '+
                          '             <tr> '+
                          '                 <td> Telefono:</td> '+
                          '                 <td><input type="text" name="telefono" readonly=true id="telefono"/></td> '+
                          '             </tr> '+
                          '         </tbody> '+
                          '     </table> '+
                          ' </fieldset> '+
                          '</form> '
                    )

                    // Imposto le proprietà della finestra
                    .dialog({
                        autoOpen: false,
                        modal: true,
                        resizable: 'false',
                        closeOnEscape: 'true',
                        width:500,
                        show:{  effect:"puff",
                                options:{direction:"right"},
                                speed:1000 },
                        hide:{  effect:"drop",
                                options:{direction:"right"},
                                speed:1000 },
                        height:350,
                        title: 'Visualizzazione Locale',
                        buttons: {  "Chiudi":   function() {
                                                    $(this).dialog("close");
                                                }
                        }
                    });

                    jQuery("#griglia-negozi").jqGrid('GridToForm', ret.idnegozio,"#order");

                    // Apro la finestra
                    $dialog.dialog('open');

--------------------------------------------------------------------------------------------------------------------------------------------

what I don't understand is why the first time it's working, the second time the form is not linked to the grid (i see the dialog but all the fields are empty)..

please help me..
