[Opensource] REPOST: Outputting elements in JSP (Marc Schipperheyn)

[Turgay Zengin]

Hi Marc,
Search the opensource archive for subjects "AttributeTag", "InputTag" and 
"ElementCollection". I have sent some files which may solve your problem 
(Brian Rook has also posted on the same subject) (Look in the June and May 
archives).

Try to change the Expresso classes with the posted ones, compile them, and 
see if your page displays well or not.

Hope this helps,
Turgay Zengin
