For some reason, when a TableView (etc) gets the focus initially (or by calling requestFocus()), it is not quite "fully" focused -- that is, it has focus, but nothing is selected.

Now, cursor keys like up/down/end/home will all respond properly and make an item of the View go into focus+selected state.

However, if you are in this initial state where there is only focus (and not selection), then keys like pg-up/pg-down donot respond... until you use atleast one of the cursor keys once (to get an item to be both focused and selected).

Expected behaviour would be that pg-down/up always function, regardless of selection.

Here's some code to help demonstrate the problem. Run it, and without using the cursor keys/tab key/mouse, try to navigate the view with pg-up/down.

This may also be related to RT-19593 -- where the scroll wheel down does not respond initially (for Views that have disabled all animations/highlights)
