-----------------------------------------

Hi,

What will that bring for you ? I don't see any benefit here.
People are complaining about the "ugly" page id in the url even now. With UUID it will be even more ugly. With Random it will be just broken because you may see someone else's session.
Can you explain what is the current problem ?
I'll answer you separately in WICKET-3554.

> The page id (Page#numericId) is an integer originating from a session scoped "sequence" (Session#pageId). This makes the page id only unique to the session.
> I think there are rationales for making the page id unique across sessions, or even globally unique (using UUID i.e.).
> One potential use case is described in the (closed) issue WICKET-3554.
> Without breaking the API backwards compatibility, some uniqueness may be introduced by using the Random class to generate pageIds. 
> But this can be greatly improved by changing the type of pageId from int to String, and use the UUID class to generate globally unique identifiers, but that will break the API compatibility....
