[Plugin: Posts 2 Posts] Access values in connection field array?

Hi scribu,

First of all; a BIG thank you for this brilliant plugin! This saved me so much work. As a matter of fact I think this should be a standard function in WordPress 4 or whatever ??

I was wundering how I can access the values in a connection field from a connection type? For example, I have the following connection type with the connection field called childtype:

$participant_connection = p2p_register_connection_type( array(
        'from' => 'post-type-parent',
		'to' => 'post-type-child',
		'fields' => array(
			'childtype' => array(
				'title' => 'Type',
				'values' => array('value1', 'value2', 'value3', 'value4','value5')
			)
		)
    ) );

Which works great by the way, I get the childtype within the loop like this:
p2p_get_meta($post->p2p_id, 'childtype', true);

But I want to get all the values from the childtype->values array outside the loop and use them in a foreach loop. Something like this:

$terms = p2p_get_meta($connected->childtype->values);
foreach($terms as $type):
  echo $type->value;
endforeach;

Obviously $terms = p2p_get_meta(childtype->values); isn’t working yet, but that’s the idea. How should I access these values?
Thanks for your time so far!

Cheers, Toine
