How to extend FiltersBean

I need to correct a core Sugar bug and I want to do it in an upgrade safe way.

The file I need to make a correction in is

modules/Filters/clients/base/datas/model/model.js

I need to comment out a portion of line 104 so that it will not perform the action for the Employees module

  

if (moduleName === 'Users' || moduleName === 'Employees') {

I have created a file

custom/modules/Filters/clients/base/datas/model/model.js

and removed all of the code except for the function that contains the code I want to alter. The problem I am having is determining the name of the object that I am extending.

  

extendsFrom: 'FiltersBean',

I used FiltersBean because that is what is says the name of the class is at the top of the file

  

/**
* @class Data.Base.FiltersBean
* @extends Data.Bean
*/

I have tried a number of different object names but cannot seem to find the correct one. Any help would be appreciated.
