Summary: Example fails

Initial Comment:
In the form input example, i now get this exception. 
Also, there don't seem to be any localized strings for
validation failures.  And in my browser, you cannot see
the failures because they are at the bottom.  Not sure
what this regression has to do with, but it's probably
a core problem.

Root cause:
