Linked Profile
Design and Skin Customization
The problem here is that there are no fields in either the profile or user datastores that links them directly to an 'owner' user. That functionality is done in another table, the 'jr_jrprofile_profile_link' table that is just two columns linking users and profiles by their IDs.
To do what you want, in the template you'd need to call the internal 'jrProfile_get_user_linked_profiles($_user_id)' function that returns an array with linked profile IDs as its keys. These key IDs need to be extracted then 'imploded' into a comma-seperated list that can be used in the jrCore_list search parameter.
So you need template code something like this -
{$linked_profile_ids = implode(',', array_keys(jrProfile_get_user_linked_profiles($_user_id)))}
{jrCore_list module="jrProfile" search="_profile_id IN `$linked_profile_ids`" pagebreak="3" page=$_post.p pager="true"}
Hope this helps
