jqGrid error on sorting datetime column

When I set [ sorttype: "datetime", datefmt: "d/m/Y H:i:s" ] to a jQuery grid, I get a message error when sorting a datetime column.

The message is: undefined. But, this only happens in IE 8/9, on Firefox it works fine.

I have some tables created dynamically. One table created is like this:

<table id="files_1">
  <thead> 
    <tr>
      <th>Sequencial</th>
      <th>File</th> 
      <th>Datetime</th>
      <th>Size</th>
    </tr>
  </thead>
  <tbody>
  <tr>
    <td>1</td>
    <td>File 1</td>
    <td>07/04/2011 09:28:00</td>
    <td>100</td>
  </tr>
  <tr>
    <td>2</td>
    <td>File 2</td>
    <td>07/03/2011 09:28:00</td>
    <td>101</td>
  </tr>
  </tbody>
</table>

After this comes a javascript function like this:

$(document).ready(开发者_Go百科function() {
    tableToGrid("#files_1", {
        height: 'auto',
        width: '100%',  
        rowNum: '2',
        rowTotal: '2', 
        hoverrows: true,
        colNames: ['', 'File', 'Datetime', 'Size (bytes)'],
        colModel: [
            {name:'Sequencial', index:'Sequencial', width: '30', stype:'text',  align: 'center', sorttype:'number'},
            {name:'File', index:'File', width: '370', stype:'text',  align: 'left'}, 
            {name:'Datetime', index:'Datetime', width: '', stype:'text',  align: 'center', datefmt: "d/m/Y H:i:s", sorttype: 'date'},
            {name:'Size', index:'Size', width: '', stype:'text', align: 'center', sorttype:'number'},
        ]
    });
});

The grid is created and works fine.

It sorts all the columns, except the datetime column.

When I try to sort this column (in IE 8 or IE 9) it returns a beautiful short message (undefined), from the grid, not a javascript error. It is as if the grid could not get some element/attribute while sorting.

Try use a complete date format information:

 {
  name:'Datetime', 
  index:'Datetime', 
  width: '', 
  formatter:'date', 
  formatoptions: {newformat:'m/d/Y'}, 
  datefmt: 'd-M-Y', 
  sorttype: 'date'
 }

There are one more simple error: comma before ] at the end of colModel definition. The combination },] is the syntax error.

The demo include the code which you posted and I see no errors at least in IE9.

You can additionally verify that in your version of jquery.jqGrid.min.js which you downloaded the following modules are included: grid.base.js, grid.common.js, grid.tbltogrid.js. To do this you can just open jquery.jqGrid.min.js in the text editor and search in the comment at the beginning of the file after the words "Modules:" for grid.base.js, grid.common.js, grid.tbltogrid.js.
