Upgrade to 2.1.2 - Paginator does not work correctly!

[ma...@rzb.at]

Hello *

I just upgraded one of my webapps from 2.1 to 2.1.2
Everything works fine except the paginator.

I get the following exception:

[10/16/03 15:57:15:234 GMT+02:00] 6c2af952 WebGroup      I SRVE0091I:

My pipeline works perfectly if the paginator transformer is on the last
position before any serializer.

But when i use any other (tried even with the log transformer) transformer
after the paginator this exception occurs
Does anybody know how to solve this or where to look after this dependency?

kind regards
