When using new forms on old data, I am not able to change a date field that has text in it. When I make the change and submit the changes, no change is made.

On App03
Look at http://si-oris-app03.si.edu/sidora/workbench/#si:2245?path=si:user-projects,si-user:57,si:2227. Edit metadata and change text in the time period date fields to valid dates and save. No error message is given and the update is not done.

when the same action is done on http://si-oris-app03.si.edu/sidora/workbench/#si:4259?path=si:user-projects,si-user:57,si:4132,si:4239 the date is updated.
