Subject Re: Pre-populating Form Bean
Date Fri, 20 Dec 2002 20:17:02 GMT
As a side note I'd watch out putting dots in your actions .. I was doing the
same and it worked .. and then i was getting an error that complained it
could find the action...

perhaps it was the release i was using or something, but i'd hate someone
else to wash time out over this as well.. If its working however then don't
fix it...
