Grails FindAllWhere with Variables
===

I am attempting to do a findAllWhere in a grails gsp passing in 2 variables: one that is the attribute and one that is the value I want that attribute to equal. I.E (author: Mark Twain) I cannot figure out the syntax and the error I am receiving does not help.

    ${Application.findAllWhere((${group1}): ${group})}

Group1 is a variable passed from the controller, and group is a variable from a g:each. Here is the error.
   

    Error 500:
