That's because your Flash tag isn't a
JSF tag. You can probably use JSTL (${dt.tops}) to get what you want, but beware - mixing plain
JSP (or JSP+JSTL) and JSF on the same page can lead to problems.
Also, fair warning. Don't use Flash as the sole means of conducting important business logic if you intend to do business with me. I almost never install Flash on my machines. So If I run into a Flash wall, I go buy from someone else.
And if you think I'm hardnosed about Flash, don't even
ask about using ActiveX. I run FoxFire under Linux and I'm quite paranoid about my system security.
Some people, when well-known sources tell them that fire will burn them, don't put their hands in the fire.
Some people, being skeptical, will put their hands in the fire, get burned, and learn not to put their hands in the fire.
And some people, believing that they know better than well-known sources, will claim it's a lie, put their hands in the fire, and continue to scream it's a lie even as their hands burn down to charred stumps.
