Bug in KeyTable?

scottn

Hi,

I am using KeyTable with Data Tables and it appears that if there is a hidden column in your table this breaks KeyTable. Tabbing through the hidden column causes 1) a null object error 2) The rest of the rows to be ignored.

The error occurs on line 397 of Data Tables:

var iRow = _fnFindDtCell( nTarget )[1];

Error: _fnFindDtCell(nTarget) is null

Am I doing something wrong? Really looks like a bug to me...

Looks like a bug to me too! KeyTable was incorrectly using the number of columns that DataTables had in it's storage for the calculations, rather than the number of visible columns. Hence the problem when you started to hide certain columns (and it would just get worse for each additional hidden column).

So I've fixed this and KeyTable 1.1.4 is now available which addresses this: http://datatables.net/plug-ins/#KeyTable

Thanks for the quick response. I will test and let you know if I encounter and issues.

Hi Allan,

There also appears to be a similure problem in fnGetPosition. The column returned does not include the visible=false columns.

However, fnUpdate does include invisible columns. So updating via the column number returned by fnGetPosition update the previous column.

[code]
var aPos = oWWMaintenanceList.fnGetPosition( this );
oWWMaintenanceList.fnUpdate( sValue, aPos[0], aPos[1] );
[/code]

fnGetPosition should give you both the index when considering hidden columns and without. The return array (for a TD node) is:

[code]
[
aoData index row,
column index (discounting hidden rows),
column index (including hidden rows)
]
[/code]
