Question

I am using ExtJS4 library to show a grid of paged data served by a Grails controller and returned as JSON.
One of the fields is a calculated field that I cannot pass back to the database for a query … because it’s calculated. What is a good solution to implement for this type of column sort request? Other columns I just pass back to the query through : list(params)

if you have a list, you can use this.

   def a = [5,3,4,2,1]
    //for asc
     a.sort{+it}
    //for des
     a.sort{-it}
