    Warning: Invalid argument supplied for foreach() in [...]/wp-content/plugins/posts-to-posts/core/type.php on line 51

    Adding the following to the expand_fields() method on a new line fixes this PHP warning.

    private function expand_fields( $fields ) {
	if(!is_array($fields)) { return array(); } // New code
	foreach ( $fields as &$field_args )

    Please add this fix in the next release. Thanks!

    Why exactly would you pass 'fields' => NON-ARRAY-VALUE to p2p_register_connection_type()?

    I used 'fields' => 'all', but now I realize I didn’t understand what the fields argument did! Just found this doc.

    Thanks ??
