I was wondering if this was a 4.x or a 3.x issue. Then it occurred to me that we should probably break the list up into 3 and 4.

I want to create a generic utility method to check whether a user is logged in, and redirect them to a login page if necessary. To do this, I need to create an ICallback in the general case. In other words, I don't know whether I'm create an ExternalCallback or a PageCallback or a DirectCallback or what have you. I just want to create a callback for whatever the current request is, if such a callback is possible. Ideally, there would be a IPage.getCallback() method, or something like it -- but I can't find one. I did find some code on the mailing list involving things like "if (this instanceof IExternalPage)" ... yuck! Surely there's a better way, and I'm just missing it? I've dug around in the docs and list archives, but can't turn anything up. ICallback isn't even mentioned in the user guide, as far as I can tell....
