Last change on this file since b6dd429 was 7125cb3, checked in by Wilmer van der Gaast <wilmer@…>, at 2008-08-24T18:01:05Z
Added SET_INVALID, which set evaluators should now return instead of NULL when the given value is not accepted. This to allow certain variables actually be set to NULL (server, for example). This should fully close #444.
Property mode set to `100644`
