Date_select bug in Rails 1.2.2

I have just upgraded to Rails 1.2.2 and date_select seems to be having a
problem. In Rails 1.2.2,

<%= date_select ‘so_header’, ‘date’ %>

expands to:

Date
2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 January February March April May June July August September October November December 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

Notice that the name of the day field is corrupted as:

name=“use_hiddendiscard_hourtruediscard_typetrueorderyearmonthdayhourminutesecondprefixso_header[date(3i)][day]”>

and therefore the date when selected cannot be parsed by ROR properly.

I have confirmed that Rails 1.1.6 works OK and the bug occurs only in
1.2.1 and 1.2.2.

Has anyone else encountered this?
