Tags exist in the Page model (or a subclass) when processing, so they
really only have access to the model layer. *However*, the Page model
has available to it the request and response objects. There are other
ways to tackle the problem, but you could try getting the information
from the response object. I believe the flash is stored in the session.
if response.session['flash'][:error]
# do something
end
