We should also check out http://jbeans.org/ for this stuff... It looks pretty cool.

Ognl will allow us to write TypeConverters for each bean and/or property, but it doesn't have a way to convert data back to a desired form (String in our case, but since this is XWork, we'll want to support any type of conversion). -Pat ----- Original Message ----- From: "Patrick Lightbody" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, October 30, 2002 4:44 PM Subject: [OS-webwork] Ognl status > OK, I was playing with Ognl today and performance became a problem. > Below is > my post to ognl-interest, I'll keep everyone posted.
