Related Field - Search

Hi all,

I extended the Calls module by a ID field pae_contact_id, linked to the Contacts Module. (see code below of the pae_vardef)

Additional I want to display & search the Contact Name and Country in the Calls List View.

Displaying the data works, but when trying to search the Country, I just get a list of all Contacts to filter on a single Contact:

What do I need to change to be able to search for e.g. all Calls where the Contact Country is "DE"

Many thanks for your help :)

Sven
