Reply To: Meta query for post object?

Ok, so I’ve narrowed it down to being a problem with my querying subfields inside a group field because I’ve tried the following:

• created a test_people post_object field outside of the authors group
• Keeping the return format as post object
• Wrap the value in an array

I’m able to get results with this code:

$author = 85;
$images_query = new WP_Query( array(
    'post_type' => 'images',
    'posts_per_page' => -1,
    'meta_query' => array(
        array(
            'key' => 'test_people',
            'value' => array( '"'.$author.'"' ),
            'compare' => 'LIKE',
        ),
    ),
));

*wrapping the value in an array causes another problem but I want to solve the first:
( Warning: trim() expects parameter 1 to be string )

The point it is, I’m not finding a way to query subfields with the function and this syntax:
'key' => 'authors_%_people'

Am I wrong in thinking groups can be treated like repeaters?
