You're trying to do something outside the scope of a web request or Tapestry
would be setting that up for you.

Hi!
I have a similar problem and I can't find the answer to my problem for
now. I want to update an existing Tapestry/Hivemind/Hibernate application
to use Honeycomb.
In my case the problem appear when I need to access the database service
inside a javax.servlet.Filter.
I get the same error message:
java.lang.NullPointerException: Property 'webRequest' of <OuterProxy for
tapestry.globals.RequestGlobals(
org.apache.tapestry.services.RequestGlobals)>

Any suggestions about this?
