Hi,

I generate in RoR an XML file representing Oracle database data, which
is then sent to an Adobe Flex UI as an HTTP Web Service. In order to
format DATES in a way that Flex understands, I add the following code
to environment.rb :

ActiveSupport::CoreExtensions::Time::Conversions::DATE_FORMATS.merge!
( :flex => '%a %b %d %H:%M:%S %Y' )

Then, I temporarily modify the formatting of my datetime data, in this
function :

def list_timespan_flexdateformat_xml
old_proc = Hash::XML_FORMATTING['datetime']
Hash::XML_FORMATTING['datetime'] = Proc.new { |datetime|
datetime.to_s(:flex2) }

@rv_wrk_calendar_events = RvWrkCalendarEvent.find(
:all, :conditions =>
[ "start_date >= ? and start_date <= ?",

params[:min_start_date], params[:max_start_date]])
render :xml => @rv_wrk_calendar_events.to_xml

Hash::XML_FORMATTING['datetime'] = old_proc
end

This works well for all Oracle DATE fields that contain TIME
information. But for some mysterious reason, it doesn't work when the
DATE field doesn't contain TIME information. The only meager result is
that some formats (e.g., '%Y %m %d', '%Y/%m/%d' or '%Y-%m-%d')
generate this :

<start_date type="datetime">2007-08-23</start_date>

instead of the default :

<start_date type="datetime">2007-08-23T00:00:00+02:00</start_date>

I tried replacing "datetime" with "time" in the code above, to no
avail...

I know I can eventually parse the date in Flex, but this problem is
driving me crazy!

Chris.
