Component used in 2 different pages and have method getParentPage

Hi, I have a problem.
I have dialog that used in 2 pages each page implements Interface
"CommonPage"
in component I have getParentPage that returns "CommonPage"
When I switch pages I have cast exception : $Page1 cannot be cast to
com.mycompany.Page2
what could be the problem?

Tapestry pages can't just be casted to individual page instances because they are dynamically 
enhanced. Cast them to their interface type or @InjectPage them.
