So, is it possible to change this gwt lib to use flashbridge and nvt at the same time?
on the javascript side the code to use the FlashBridge is just one line, all the subscription/update handling logic is done on the flash side:
[SYNTAX="JS"]new FlashBridge("flashObjectId");[/SYNTAX]
(see
http://www.lightstreamer.com/docs/client_flash_jsdoc/FlashBridge.html#FlashBridge() )
so it should be easy to add it to a GWT application. Obviously you also have to put the appropriate flash object on the page.
On the other hand you can't exploit a single subscription to fed both your NonVisualTable (js) and your FlashTable (as) so you'll have one subscription per *Table object.
An alternative would be to use the adobe's FABridge to directly pass updates from the NonVisualTable's update handler to your flash object. I see there is also a GWT version of such bridge:
