No way for the redirect. That starts a new request, and Youmust tell the 
client to send the data. The simplest way is to put them in the request:

return context.REQUEST.RESPONSE.redirect(request.URL1 + '/myPage?errorMessage='+errorMessage)

(errorMessage must be URL-encoded in this case ...)

and in the template say something like:

<p tal:condition="options/errorMessage | request/errorMessae | nothing"
   tal:content="options/errorMessage | request/errorMessage">Error message</p>


But why do you need the redirect at all? Does 
"context.myPage(errorMessage='some error message')" not work?

Hm, looks like you need to store the data in the session ... that is
what is has been invented for ;-)
