When creating a new link or editing an existing one, if you select a shared resource as the picture, the following error happens when validating the dialog :

No directory: /home/glefebvre/bin/AmetysV4M2/webapp/cms/WEB-INF/data/uploads-user/admin/resource:/80f7fc48-0528-4e20-a2a5-bc07981b0474
java.util.NoSuchElementException: No directory: /home/glefebvre/bin/AmetysV4M2/webapp/cms/WEB-INF/data/uploads-user/admin/resource:/80f7fc48-0528-4e20-a2a5-bc07981b0474

This happens with the default resources or the custom resources uploaded before in the "shared resources" category
