Reverse routing Date objects uses wrong format

Reported by Dirk | October 12th, 2010 @ 01:15 AM | in 1.1

If I pass a date parameter as part of a reverse route, the url that is
constructed will not output the date using the format I set
date.format in application.conf:


public static void feed(Date date) { ... }

/pets/{date}/feed Pets.feed


/pets/2010-10-11 10:55:05.0/feed

The reason seems to be that somewhere along the line the Date is
converted into a java.sql.Timestamp. When the reverse router turns
this into a String it uses the toString() method, instead of using the

If I go to the generated url, play attempts to convert the String to a
Date using DateBinder, and fails, giving me null.

Apart from this bug, I have a question: Why does Play use the
configured date.format value for urls? Maybe it would be better to
just convert all Date and Timestamp variants into their milli-seconds
since the epoch equivalents?
