It could be changed, if it's thought worth it, once we are on 2.8. You need a package level type alias (and def pointing to the factory). Change the name to PageVar and add some deprecated aliases. But it would be silly. Someone needed a feature--accessing a RequestVar from ajax. So now its semantics were changed to be a page var, while adding an actual request var under the name TransientRequestVar, as internal API. Now we'll rename RequestVar to PageVar? Musical chairs anyone? What should really happen, or at least have happened, is that when someone wanted the semantics of a page var in a RequestVar, instead of changing RequestVar, a new class called PageVar should have been created. As they say, hindsight is 20/20...

I've had this desire, though I ended up working around it. I think that RequestVar should really be PageVar, but unfortunately I think RequestVar is fairly set in stone at this point. -Ross -- You received this message because you are subscribed to the Google Groups "Lift" group.
