Subject Re: Struts 2 Multi Level Type Conversion
Date Thu, 20 Dec 2007 11:21:55 GMT

hi,
i had the same problem
(http://forums.opensymphony.com/thread.jspa?threadID=184150&tstart=0) try
creating a file: Calender-conversion.properties at location: /java/util/
(i.e. assuming location of calendar @: java.util.calender and assuming
calendar is the object type of the field variable in ur action class.) This
should work, but not sure why for this absurd behavior. 

cheers,
ravi
