when iterating over the subcomponents, use 'subcomp' rather than
2001-10-24 Damon Chaplin <damon@ximian.com> * pcs/cal-backend-file.c (cal_backend_file_update_objects): when iterating over the subcomponents, use 'subcomp' rather than 'icalcomp'. That meant it wasn't working at all well when an entire VCALENDAR was passed in. * cal-util/cal-component.c: handle DURATION property used instead of DTEND or DUE. In cal_component_get_dtend/due we will return DTSTART + DURATION if necessary. In set_dtend/due we remove any DURATION property. Fixes bug #11262. * gui/e-meeting-model.c (build_etable): * gui/e-calendar-table.c (e_calendar_table_init): use U_ for the ECellCombo popdown strings, as it expects UTF-8 strings. svn path=/trunk/; revision=13992
