following upgrade to 2.x, no longer shows results

I had version 1.2 of this module working, but when I upgraded to 2.1, it stopped returning results. The view structure is as follows:

$view = new view;
$view->name = 'reviews_by_article';
$view->description = 'Displays all Review content that comes from a given Article';
$view->tag = '';
$view->view_php = '';
$view->base_table = 'node';
$view->is_cacheable = FALSE;
$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');
$handler->override_option('fields', array(

$handler->override_option('types', array(

));
$handler->override_option('modes', array(
'0' => 'full',
));
$handler->override_option('argument_mode', 'nid');
$handler->override_option('default_argument', '');

If I give it a valid argument, the preview SQL looks like this:

SELECT node.nid AS nid
FROM node node
LEFT JOIN content_type_review node_data_field_source_article ON node.vid = node_data_field_source_article.vid
WHERE (node.type in ('review')) AND (node_data_field_source_article.field_source_article_nid = 30)

If I run that SQL directly in the database, it returns 14 node ids. If I change the row style to fields (instead of nodes), I can get the results to show in the default display (preview) but not in the node content display. Changing the row style back to nodes (which is what I need) gets me an unhelpful AJAX error in the default display and still nothing in the node content display.

I'm going to try downgrading to 1.2 for now. Suggestions welcome!
