Re: [xwiki-devs] Looking for help with groovy

      I feel like I am so close, but it just is not working.  I have the following
code but it is throwing an error.  I will attach a screenshot of the error. 
(My company is blocking SSH all of a sudden. So I cannot copy the file.)  It
is saying there is no such property.  I assume it means the "xredirect"?
