Update problems of my Rails3 application to Rails4

[Philipp Näö]

Hey,

I'm trying to update my Rails3 application to Rails4, but somehow some standard behavior of Rails seems to be changed,
although I couldn't find anything in the update documentation.

I've already described my problem on StackOverflow, but noone could help. So I'm just linking to it in the hope someone of you can help me :)

Thanks a lot, yeah, it solved it. Spend to much time on that issue. Just as question for the next time: Have I overseen this update in the update documentation or where can I find such changes?
