corona sdk, parse.com, relation

I am using corona sdk with parse.com

After I add object to relation table, I can access the table in browser by clicking View Relations. However, how can i access the table in Corona? right now when i query all the data fields, I can only access something like this:

MY_FRIENDS:

__type: Relation

className: _User

But not the actual objects within the relation table…

How to get objects within the relation table?

thanks in advance
