Changeset 6396 for main/waeup.sirp/trunk/src/waeup/sirp/browser

Timestamp:

Message:

Provide left sidebar links for applicants instead of action buttons. Only officers see the action buttons.

The LeftSidebarLink? baseclass does now also provide an icon_url which will be needed in the students section.
