Testing issue with creating a view/layout

Bad subject line, but not sure what would be better.

My issue only seems to happen in testing and I want to see if I can
find a way to fix it.
My rails app will host many domains each with its own layout. (stored
as layouts/sites/ID.html.haml)
This layout is generated when the site instance is created. When
testing, rails does not pick up the fact that there is a new layout
available.

Example using cucumber...

Given there is a site known as "site1"
When I am on the press releases page

The layout is generated and save in the first step. The 2nd step a
simple webrat visit doesn't see the new layout. Even if I premake the
layout before running the feature, the webrat step does not see the
updates.

Is there anyway around this? How does one force rails to "refresh" the
views/layouts?

Rails normally checks on each "hit", but it seems the webrat hits are
different, like all in one session.

Many thanks..
