I reviewed the Core book again today to look at the Tiles section. Looks like I am going to have
to make the WizardController in my scenario (which is deciding which panel to include in the
wizard layout, which stays the same) into a TilesController and then it should be ok.
My question is why on Earth do we have to do this? What is the point of having an EL if you
can't use it for something like this? Tiles looks like a good solution to other problems, but
for this I would prefer that dynamic content inclusion through a simple include tag and EL
would just work!
Thanks.

No, that should not be the reason. In tiles example we also have <f:subview/> only in *template* JSP file.
One hint could be, that inside of JSTL you can't access faces-config.xml
So why not using Tiles with Apache MyFaces?

Subject: EL w/<c:import/>
Here's the part of the page I am trying to get working:
<f:subview id="labApplicationPanelInfo">
<c:import url="${sessionScope.labApplicationWizard.currentPanel}"/>
</f:subview>
I did some reading about using EL and found the pieces that would allow me
to stipulate the URL dynamically. When I first got the pieces in place and
tried it with MyFaces, it blew up with an error saying it couldn't find the
servlet path for the URL (but w/jsp on the end). I did some searches and
there was some talk of a fix for it (I even found a diff of the source
checked in on 3/10 to fix this problem). So I synced with CVS and built
everything and tried it again. The results this time are much more
spectacular failure, including some of the craziest stack traces I've ever
seen (looks like an endless loop). Here's an excerpt:

I stuck my head into some of the code to see what was causing this but no
luck yet. Any thoughts appreciated.....
