reordering items between columns works just fine, but save changes does not (in fact it switches back to normal grid view - i suspect that is erroneous too?)
here is a bit of the logfile that seems connected:
2012-11-20 11:12:50,162 Trac[web_ui] DEBUG: WhiteboardModule: field=status
2012-11-20 11:12:50,162 Trac[web_ui] DEBUG: WhiteboardModule: changes=3:accepted,
2012-11-20 11:12:50,162 Trac[web_ui] DEBUG: WhiteboardModule: change_items=[u'3', u'accepted']
I tried to change the state of a ticket from new to accepted.
