Updated uwl.collaboration.xml but can't see any change

Hello,

at the UWL configuration there are 3 xml files which can be modified in order to modify the User view.

I have followed the instructions at this PDF in order to modify the collaboration view:

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/xi/how to configure the universal worklist.pdf

I have uploaded new uwl.collaboration.xml xml with medium priority by the name uwl.collaboration_test.xml and cleared the UWL cache (even restarted the server) but I don't see that the modification is taking place.

Has anyone got a chance to deal with these xmls? Should I do something more in order to commit my costumized xml to the User's view?
