Subject Re: Eliminate Setup Actions
Date Sat, 05 Mar 2005 21:17:00 GMT
I think this solution is "the bomb".  I once suggested a generic
solution like this for Struts called StrutsState.  No one was much
interested, so I just built it for my own work.  It is so helpful that
I cannot express my gratitude toward myself to myself.  ///;-)
