title: Using g.render in a grails service
body: <p>I'm trying to use g.render in a grails service, but it appears that g is not provided to services by default.  Is there a way to get the templating engine to render a view in the service?  I may be going about this the wrong way.  What I'm looking to to is render the view from a partial template to a string, and send the resulting string back as part of a JSON response to be used with AJAX updates.</p>
  
  <p>Any thoughts?</p>
