Server-Side scripting on file upload not triggered in v2

Hi guys,

On image upload I am using a server-side script to generate a thumbnail and different sizes of the image uploaded.
After migrating to version 2.0.1-1, after the upload the server-side script is not triggered anymore.

I have tried both pre and post process (the snapshot is for "files.{folder_path}.post.post_process") but it seems that this feature is not there anymore.
Event based scripting is working for the other services, but not for the file service. I have tried both on my hosted environment (ubuntu 14.0 x64) and on the 1 hour AWS demo.

Maybe I do something wrong. Any advice would be greatly appreciated.
