What doesn't work yet: * If you delete all characters in the date box, you'll get an error message. This will go away if you type more characters * You'll get an error as above when the form is cleared and redisplayed after submission. Again, it will go away if you type anything in the box. * Validation doesn't work, but the preview will display "Invalid date" if Chronic can't parse your phrase * This isn't added to the edit form for actions yet. Also partially fixed #394: the mobile interface works again, but you might get an error visiting the subsequent pages of a filtered view (i.e. viewing a single context or project). I'm not sure what's causing this, but it's on my list to fix. git-svn-id: http://www.rousette.org.uk/svn/tracks-repos/trunk@332 a4c988fc-2ded-0310-b66e-134b36920a42
