States and Bitmap.Draw

Question

I'm attempting to use states to reformat a canvas for
printing/exporting.
The idea is to be able to export an image of the canvas as
below
c:Canvas has 2 states - null (base) and "Print".
c.currentState = "Print";
save(c);
c.currentState = "";
Where saveim is a custom function that takes care of all the
saving details, but essentially takes a snapshot with Bitmap.draw .
The problem is that some state change elements don't seem to
change fast enough.
Changing the visibility of a child of 'c' in the state
definition works fine, but changing "includeInLayout" doesn't
appear to get called at the same time.
1. I've ensured that the desired state is reached (by not
restoring the state afterwards).
2. I've tried moving the save comment into a
StateChangeEvent.CURRENT_STATE_CHANGE event listener, but that
still seems to be too early.
I'm guessing the page actually needs to be rendered before
the layout is updated. If that's so, how can I ensure this happens
before save is called? If not, then what triggers the layout update
and can I listen for it?

Answer 1

no.
The idea is to reformat to a print friendly layout, take an
image, then change the format back with minimal impact on the user
(Ideally with no visual change, but I could live with a breif
flicker).
