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

This is really a better question for the Struts2 folks. WebWork 2.x
must have had an event handler configured to automatically silence
references that resolve to null/void, because
ServletRequest.setAttribute(...) has always returned void. Either
that or $req was a wrapper for ServletRequest that returned an empty
string.
For dealing with this, you can either set up a
ReferenceInsertionEventHandler to suppress these or, as i would
recommend, take Claude's suggestion and just use silent notation
$!req.setAttribute('blah', $blah)

It's because they are not resolved. Have you tried with $request instead
of $req ?
Even when unresolved, you can avoid such statements to leak on web pages
by using "$!req.setAtt..." (you should still be warned in the logs).
