I went ahead and wrote an interceptor. The only problem I have with doing it this way though is that the interceptor is doing some magic that isn't quite apparent when looking at the JSP / OGNL code. > > We can set properties directly to the stack from an Interceptor.

Yeah, I agree with that, but in my case this is a sitemesh decorator page. I am rendering a menu based on the section of the site they are using. Each namespace is like a 'module,' so I figure if the user is looking at namespace X, they are presented with a menu that corresponds to namespace X. I just didn't realize at design time that there wasn't a quick way to get the namespace within OGNL. > > Note that the value stack properties are exposed as request > properties, so any property set should be available to the tags and > JSTL without any weird OGNL syntax. > I can normally get what I want pretty easily with OGNL. This call was a bit more complex but I still don't understand why it doesn't work. I'm happy with my current solution, but was hoping someone could explain what is wrong with the expression as I had it originally. -Wes > HTH, Ted > * <http://www.StrutsMentor.com/> > > On Jan 7, 2008 2:36 PM, Wes Wannemacher <[EMAIL PROTECTED]> wrote: > > Hello, > > > > I have been struggling to find a way to see what the namespace is from > > within a JSP.
