Version: 4.2.4 (using KDE 4.2.4) Installed from: Ubuntu Packages If none of the available calendar resources are available, it is not possible to add todos, events, or journal entries. There is no error produced, the "add event" dialogue appears properly, but the user can't press "ok", or "apply", so the event will not be added. I'm not sure how this happened to me, must have been something to do with the upgrade from 3.5.x, but it's easy to reporoduce: 1. Add new calendar resource 2. Select "use calendar as default" in the context menu for the new calendar. 3. Delete the new calendar. No new default will be selected. Suggested fixes: 1. Check for a default calendar resource on start up, and on calendar delete/change, 2. If there's no default, give the user the option to select an existing one, or create a new one if none exist.
In 4.6, the event dialog is independent from selection. Just choose the collection in the combo, doesn't matter if it's selected or not.
