Uncaught TypeError: Cannot read property 'nTr' of undefined

Using Google Chrome 11.

Am new to DT, however have just started a project using 1.7.6, and is here:

(click on markets, updates are every two seconds)

When I use the same code with 1.8.0 beta 3, get the error messages.

here's where the exception occurs...

[code]
for ( iRow=iStart ; iRow

Hi there,

I debugged into DataTables where the error was occuring, and noted iEnd becomes 11, not 4.

[code]
line 5876
function _fnGetTdNodes ( oSettings, iIndividualRow )
{
var anReturn = [];
var iCorrector;
var anTds;
var iRow, iRows=oSettings.aoData.length,
iColumn, iColumns, oData, sNodeName, iStart=0, iEnd=iRows; // <<<<< iRows = 4

/* Allow the collection to be limited to just one row */
if ( typeof iIndividualRow != 'undefined' )
{
iStart = iIndividualRow;
iEnd = iIndividualRow+1; // <<<<<<<<<<<<<<< iIndividualRow = "1", so "1" + 1 = 11, ooooops!
}

for ( iRow=iStart ; iRow

Ah, the power of open-source!

I hacked line 5891 to limit the loop to iRows, not iEnd. Does the trick for me, but no doubt there was a reason for calculating iEnd, so will leave it to you to update correctly, with your unit tests. Maybe need a new unit test in this area - how come it passed? ;-)

[code]
function _fnGetTdNodes ( oSettings, iIndividualRow )
{
var anReturn = [];
var iCorrector;
var anTds;
var iRow, iRows=oSettings.aoData.length,
iColumn, iColumns, oData, sNodeName, iStart=0, iEnd=iRows;

/* Allow the collection to be limited to just one row */
if ( typeof iIndividualRow != 'undefined' )
{
iStart = iIndividualRow;
iEnd = iIndividualRow+1;
}

// for ( iRow=iStart ; iRow

I see - so the basic issue is that 'rowid' that you are passing into fnUpdate is a string rather than an integer? The problem with that is that fnUpdate isn't expecting a string - it is looking for an integer or a DOM node. Currently it looks like giving it a string results in undefined behaviour (and weird things happen as you are seeing). So the question is, why pass in a string to fnUpdate?

Thanks, spot on. Going back to the server side and making sure row IDs for updates are being outputted as integers (via JSON) did the trick. Many thanks!

Wow.Bang on! Thanks. Solved my issue I was passing string instead of int to fnUpdate
