knockout and datatable stop working after sorting

kenneth_eagle

I found an interesting behavior with the knockout prototype, http://datatables.net/dev/knockout/.
The prototype stop working after re-sort the table. I used setTimeout for updating a field after 5 sec. Within that 5 sec time range, I sort the table to a different order, then field won't get updated. Does anyone experiencing the same problem?

Just found out setting all rows to invalidate instead of setting 1 row invalidate will fix the problem. Not sure will this affect performance.

$.each(this, function (key, value) {
self[key].subscribe(function (val) {

// Find the row in the DataTable and invalidate it, which will cause DataTables to re-read the data
//var rowIdx = dt.column(0).data().indexOf(self.Id());
//dt.row(rowIdx).invalidate();

// set all rows invalidate
dt.rows().invalidate();
});
});

A full invalidate will hit performance a bit, but it won't be too bad unless you have a really large table.

I've been working on a `dt-foreach` binding which might be a bit more intuitive with Knockout rather than the horrendous mess of the observable arrays and objects.

Could you drop me a message ( http://datatables.net/contact ) with your e-mail address if you are interested in taking an early look at it?
