Ok i made it work.
The problem was that i defined flow (outcomes) in pages.xml
It was simple navigation with rule - not some fancy tricks around it.
When i moved navigation to faces-config.xml (actually in other standard config file for JSF definded in web.xml) everything works like a charm.
This can be my mistake but i checked houndred of possibilities - this one works.
If anyone have any idea why or encaured similar problems when defining navigation in pages.xml please post.
