Has anyone written a decent one?

I had an app that worked fine in 1.3, in 1.4 the focussing is a disaster.
I have JDesktop panes, JIternalPanes and JTabbed panes containing JTables,
JComboBoxes, JTextFields etc.

Using ContainerOrderFocusPolicy I can't get initial focus to work, it's take
2 or 3 tabs sometimes to move from one component to the next etc. I guess
it's stepping out to parent panes and then back or something even though
I've set everything to focusable(false) except the items I want to land on.
I wrote a pretty basic policy but it's not handling compound components
properly (a JComboBox I've made AutoCompletable) and I haven't covered any
of the up/down cycle stuff or checked for no enabled components. Does anyone
have anything more complete? (I'm no swing expert)

Cheers, Richard.
