grid filters gives me GET 404 feature/filters.js not found

[treemonster19]

the same issue is encountered by many others, but seem like no solution to this

my extjs version 4.2.0
1. i am trying to add basic filter in my grid, so suppose if i include ext-all-debug.js i dont need to use Ext.require ?
but i tried both ways.

I get GET 404 error saying http://localhost/feature/filters.js not found, but this file is not present in extjs package.

pls help

UX components aren't included in the main source directory. You can copy them as needed from the /examples/ux directory of your Ext JS folder.

Filters are found in /examples/ux/grid.
