Modifying View using AJAX pagination ...

This is an interesting issue and I can't quite pin down the point of failure. I have a view that is sorting data from node_counter, but some of the node_counter_totalcount data has null values. The query executes fine and the $view->total_rows value reports the correct row count, but the records that have the null values appear to be excluded from the display of the view. I've included the view definition below on the chance that might be helpful.

$view = new view;
$view->name = 'faceplates';
$view->description = 'faceplates';
$view->tag = 'faceplates';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = '0';
$view->api_version = 2;
$view->disabled = FALSE; /* Edit this to true to make a default view disabled initially */
$handler = $view->new_display('default', 'Defaults', 'default');
