Problem with custom post type list

Hello,

I have a problem with custom post type – excerpts are not visible when i’m using a function: the_user_favorites_list($user_id = null, $site_id = null, $include_links = true, $include_thumbnails = true, $include_excerpts = true, $filters = $filters)

I have also other custom post field, which are not visible, so I’m looking for another solution – is it possible to retreive the IDs of favorites posts from current logged in user?

If I have Ids i would be able to create custom query with all needed informations.

Thanks for any help.
Peter.
