FiltersFeature.js - 404 Not Found

Hello,

We are migrating a Web Application from ExtJs 4 to ExtJs 5.

We had to change some paths inside the index.html to get rid of some "404 Not Found" errors regarding the ExtJs5 files. But this error didnt vanish:

"NetworkError: 404 Not Found - http://localhost:8080/ext/build/examples/ux/grid/FiltersFeature.js?_dc=1414145245733"

I have looked into the Path and there is no such js-file. Where is it and how to get rid of the error ?

Thanks in advance
