Unknown error in DataTable

jtop

DataTable v1.9.4
jQuery v1.8.2

When DataTable runs, it tried to process _fnStringToCss( s ) method and its fine until it eventually the value of 's' is reference to the actual table dom object. In this case it blows up on the line s.charCodeAt(s.length-1). Do you have any ideas why this is the case. I've included my datatable code below for reference.

Uncaught TypeError: Object [object Object] has no method 'charCodeAt'

$('#incentives-table').dataTable({

Likely your forcing the type of a column means that one of the internal functions is failing. For example if you force a column to be a 'string' and it has numeric data in it, it will likely cause a problem.

Please link to a test case so we can say for certain what the issue is rather than just guessing.

Allan,

Thanks for the insite. That is exactly what I found to be the problem. I had defined a column wrong in my json. the date i thought was coming back as a formatted string, but was being returned as a long value.
