Hmm, yeah that seems like a loop. I just tried the same think and the
same happens to me.=20

Then I looked into site.xml and found:
<forrestPlugins label=3D"Plugins Index" href=3D"site:forrest/plugins"
description=3D"Index of Forrest Plugins"/>

I changed this to=20
<!--<forrestPlugins label=3D"Plugins Index" href=3D"site:forrest/plugins"
description=3D"Index of Forrest Plugins"/>-->

...and voila, it is working. Then I remembered finally that somebody
reported stack overflows with the dispatcher and found:
http://issues.apache.org/jira/browse/FOR-738

This seems to be the cause of your problems, v2 is again not working
with site: in general (I did some tests with the lenya.zones site [based
on v2]). Maybe it is because of the indirections of lm and v2, but it
seems to be more, once again, the jxpath problem.

We need to see what gives v3 with the site:, but if it is fixed there it
wont fix in v2, if not we need to dig in again why Davids workaround for
site: is not working anymore.
