Failed to get id id from undefined or null reference

I am trying to create an Ext.PagingToolbar that works fine in all major browsers, including IE9 and IE 10. But in IE 8 and below, it ends with the following error .

Unable to get property id 'w90> or null reference

When I track, I found that an error occurs in the following code.

var cm = new Ext.grid.ColumnModel({ defaults: { sortable: true }, columns: [ { header: 'Result Set', dataIndex: 'result_set_name' }, { header: 'Result Date', dataIndex: 'result_date', xtype: 'datecolumn', format: 'm/d/Y', dateFormat: 'c' }, { header: 'Comments', dataIndex: 'comments' }, { header: 'Link', dataIndex: 'link', renderer: function(value, metaData, record, rowIndex, colIndex, store) {return '<a href="'+value+'">'+value+'</a>';} }, ] });

But I can not find the source of the problem and what needs to be done. Any help is appreciated.

Your mistake is that you end the array of columns with a comma, which leads to such an error. IE is trying to read an object after the decimal point, which will be undefined
