Okay, I've set this up in my ApplicationServlet's init() method
Registry myRegistry = RegistryBuilder.constructDefaultRegistry();
PCTAdminApplicationServlet.asm =
(ApplicationStateManager)myRegistry.getService(ApplicationStateManager.class);
then i have this in a new method I made called getAdminVisit()
---------------
AdminVisit aVisit = (AdminVisit) PCTAdminApplicationServlet.asm.get("visit");
if (aVisit == null)
aVisit = new AdminVisit();
PCTAdminApplicationServlet.asm.store("visit", aVisit);
return aVisit;
--------------
However, I get a null pointer exception on the very first line there. Any
ideas? I find where Tapestry and Hivemind meet is very hard to get any
documentation on, it's like a fringe area...
Thanks,
Greg

Another option would be to create a singleton to hold onto tapestry's
hivemind registry, you can do this in your ApplicationServlet. Then
access ApplicationStateManager object via the registry, thus set/get
your Visit state object at any point in the app.
i.e. Visit visit =
(Visit)((ApplicationStateManager)this.myRegistry.getService(ApplicationStateManager.class)).get("visit");
