Can't display a row after fnAddDataAndDisplay

Can't display a row after fnAddDataAndDisplay

edited February 2012 in DataTables 1.9
I have a table that retrieves a Json array via Ajax. It allows editing and adding records via dialog edit forms. After an edit, I use API plugin code like this:

oTable.fnDisplayRow(oTable.fnGetNodes(index));
(I've retrieved the index by stepping through fnGetData to find the key.) This works fine.

However, when I *add* a data row using code like this:

oTable.fnAddDataAndDisplay(row); // from the plugin
..the row doesn't appear.

I've verified that the index is set correctly and the row exists. And I can filter for it with sSearch or fnFilter, or manually page through to it.

I believe this is because the nTr isn't going to exist on a row that's never been displayed -- so since oTable.fnSettings().aoData[index].nTr is null, fnDisplayRow(fnDisplayRow(oTable.fnSettings().aoData[index].nTr) is going to fail. The line in the plugin:

var nAdded = oSettings.aoData[ iAdded ].nTr;
is also producing a null. iAdded is correctly calculated.

Any idea what's wrong with my new table row? Stepping through code now but if you happen to have seen this before...

Thanks!

    Still fussing with this -- FWIW, it seems that it's unrelated to the fact of having just added a row. Only the first 29 rows produce non-null nTr results.

    Simple enough solution, I just added a

    oTable.fnPageChange( 'last' );
    before the row navigation. But I'd love to know what I was doing wrong!
