why do $req.setAttribute()s show up in my html page

[Betty Chang]

Hi --

I'm sort of a newbie to both struts and velocity.  I converted an existing 
webwork2.2.4/velocity project to struts2/velocity.  Things seem okay except 
that my $req.setAttribute("blah",$blah) calls in my .vm files end up showing up 
on my html page.

Is there something I need to set to avoid this?   (They did not show up with 
webwork2.2.4)

Thanks

Betty
