Using column.render when no data is present

mikeosoft

I have some checkbox columns which I want to render specific string if checked. However the table is initially empty and fills up when the user adds data along time.
This combination leads to an alert box saying "Requested unknown parameter....".

It seems that if I remove the rendering function, the error goes away.
Is there a way to avoid the alert message?

Hi @mikeosoft ,

That sounds odd, would you be able to on link to a test case that shows that problem?

Cheers,

Here it is

I used my editor js files because it seems those on the examples pages are not the same code.

As a side note, the problem happen when I want to add a new line, via method addNewLineHabiletes

Most likely you need to use columns.defaultContent to tell DataTables what data it should use if there isn't a data point for the column in question for the current row.

I don't actually check a conditional check on a checkbox value in your rendering functions and the code doesn't actually run for me, so I'm not certain where the error is. Can you copy / paste the error message in please?

Hi,
The defaultContent did the trick! Thank you

FYI, the message was : DataTables warning: table id=tab_174f418de0e04b5b832a774aff803f49tableHabiletes - Requested unknown parameter 'estAssistant' for row 0, column 1. For more information about this error, please see http://datatables.net/tn/4
