The renderDateTimeField macro in htmlFormMacroLibrary.ftl ignores the
framework date-time format settings and formats date-time fields using
jQuery instead. Two problems with that:
1. Even when shortDateInput = true, the date and time are displayed when
the value is a Timestamp.
2. If the value is anything other than a Timestamp, (java.util.Date or
java.sql.Date) then the field content is localized, and any attempt to
pass the field content to a service fails - because there is no way to
convert the string back to the proper object type.
Why was this change made?
I located the problem and committed some notes in rev 1197028. I don't
have time right now to fix it.
