Steps to reproduce

• Create a content type with a repeater (you can use "contacts" repeater from AbstractProgram then modify it to add the following header-label: <cms:header-label>{role}</cms:header-label>)
  • This repeater should have at least one element of type "content"
  • Add a header-label with this element
• Create a content of this type with something inside the repeater (or reuse ODF demo data)
• Launch a search (Solr search for example) with the repeater as a column (content-type: "Program", query: *:*, columns: title, contacts).
• The result column of the repeater is displayed with its ID instead of its title. Title is well used in the repeater header label during edition.
