yeah. default impl. of isStateless should do this instead of return false

a page knows if it has statefull components.
Then the Page.urlFor(Component,interface) is called.
Or do i not see something here? IF that is not called then there is no
callback from the page.
If that is called somehow then it could be some kind of interface from
a component (Link click, Form submit or any interface)
and then the page is statefull because a callback can happen.
I think we just record that for a page. (IF
urlFor(Component,interface) is called) If not then a page is stateless
and it is not stored
in the page map. If it is called it has to be added to the pagemap.

maybe when the component check flag is on we could look for any
