How to reproduce:

• Create a content 1 of type A
• Create a content 2 of type B, with a link to content 1 via an attribute (configured explicitely to point on type A)
• In the default-edition view (or main if default-edition does not exist) of type A, add a system property
• Open the solr search tool, search for contents of type B, with the content attribute in columns
• The content 2 is retrived, with the content 1 in the corresponding column => OK
• Clic on the pen next to content 1 to modify it.
• An error occurs while opening the modifying dialog box, an NPE because some item in the type A main view does not have model (it is the system property) =>KO
