Here’s another recent topic, http://support.advancedcustomfields.com/forums/topic/acf-pro-options-pages-with-repeaters-not-working/, but I do remember others that use genesis having this problem.
But this is usually a problem when people try to use get_field to return then entire array and not something that is usually a problem when using the acf have_rows and while loop, so this is a little confusing and I’m not sure that it’s the same issue or that my first post is right
It should work no matter what is in $post_object (object or ID) but you could try
if( $post_object ):
if( have_rows('project_images', $post_object->ID) ):
while ( have_rows('project_images', $post_object->ID) ) : the_row();
the_sub_field('project_image');
endwhile;
endif;
endif;
The only other thing I see to ask about is what it the ‘project_image’ sub field set to return, an image array, ID or URL?
