When Query is null (URL parameter parsing/escaping error?)

[David Rauschenbach]

I've been unable to access parameters from my Handler.  
Request.getResourceRef().getQuery() returns null, and
Request.getResourceRef().getQueryAsForm() returns a Form with a null delegate.

My URL is provided by ActiveResource (Rails trunk around r6039), as follows:
  
http://localhost:8100/searches/cat.xml?repositories[]=%2Fvar%2Fsvnapp%2Fdrr&repositories[]=%2Fvar%2Fsvnapp%2Ffoo&offset=10&limit=10

Maybe the forward slash escaping is not getting through?
