[Trinidad] how to trigger PPR manually

[Renzo Tomaselli]

Hi, I'm looking for a method to trigger PPR upon setting certain 
conditions on client operations.
I have a multipanel page, where one panel contains an iframe for 
rendering a blob through browser plugins.
Users are allowed to swap, minimize and restore panels through js, thus 
these operations are purely client-bound.
When the Adobe plugin is involved to manage iframe contents (both on IE 
and FF), the iframe area is not refreshed after its panel is restored or 
swapped.
Don't ask me why.
Thus I need to force a refresh, and this would be much better if 
partial, e.g. concerning only that panel.
How can I trigger it from js ?
Thanks -- Renzo
