source: main/waeup.sirp/trunk/src/waeup/sirp/applicants/interfaces.py @ 6128

Last change on this file since 6128 was 6111, checked in by Henrik Bettermann, 14 years ago

Use APPLICATION_TYPES for both application_types_vocab and application_pins_vocab. This will ease the configuration and force officers not mix prefixes.

applicantscontainermanagepage.pt: Add missing colon.

865      <MyContainerProvider object at 0x...>
