Page id unique across sessions (or even globally unique)
--------------------------------------------------------
Key: WICKET-4452
URL: https://issues.apache.org/jira/browse/WICKET-4452
Project: Wicket
Issue Type: Improvement
Reporter: Erik Godding Boye
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....
