How to reproduce

• open BO
• add the search service in a page
• in the parameters we were using people from user directory
• In the search on section, we defined a page, the root of the user directory (it is useless but it was done like that)
• validate
• search on FO
• First page is displayed
• click on the second page or the next page

Actual behavior

• the list is empty

Actually in the code of the form, there is the path of the selected page instead of the id

Have a look to the "template form-search-element-pages"
