it appears that paintedItemListener can be called before the
corresponding item (cell) is intialized. is this expected behavior? or a
bug?

ya. what i'll do is attempt to get everything working in some fashion,
possibly with changes to the widget/viewer sources. then i'll have a
better sense of all the problems and potential solutions.

hopefully i'll be able to do the above and file the bug within a week.

This is certainly possible behavior...
These events are fired when the container updates its internal
"paintedItems" list by determining which items will be painted to the
screen and which will not. Depending on the implementation, the cell
may wait to initialize until it is painted, in which case
paintedItemListener is called before it is ready to actually be painted.
I think the bigger problem here is that cells do not have a well defined
series of life-cycle events (partly because once you and Cal started
using them, it became apparent that the initial sequence was inadequate
:) ). This problem is also at the heart of your other issue with
getting events for your viewers' creation and disposal, and even the
order in which they initialize.
Please file a bug for this and add your thoughts on what will suit your
use cases best.
