Hi there, Actually when you are looking at the stuff done in the JSTL all three ways pretty much work, because it contains a scripting language ;).
Are there any plans on integrating it within Struts? I like
both libraries very much, and I recall a discussion was going
on a while ago about it?
If it is done this would make it is either:
1. property = "all I want to write"
2. property = "<%= java expression %>"
3. property = "${myRadios[param.index]}"
(here with 'index' as a request variable ;))
