[Wicket-user] Scope of application object

[Frank Silbermann]

Others have asked about sharing information between pages, and the answer has been to pass the shared information via page constructors.  Since no one suggested using the WebApplication object, does that imply that this is a singleton shared by all clients?   It has been said that it is poor form to access the Session directly; one should pass page parameters instead.  I imagine this is analogous to the programming language dictum of “loose coupling” – that one should use pass information in subroutine parameters rather than through shared global variables.   However, if you have many pages, and a piece of the model is shared by _all_ of them, would this be an exception to the rule?  If so, what is the code for creating and accessing “global” session-scope objects?   /Frank
