Hi,
I just realized that any event occurs in WD triggers data refreshing in flash, the flash island BEGIN_UPDATE and END_UPDATE events fire and all the set funtion get called, even though the context nodes bound to flash data objects haven't changed. Is this normal and why is it like this?
Besides, can anyone provide a document or link or anything that explains in detail how the island library works. Thanks in advance.

Yes

Because there is no delta handling cacluation on the xBCML data stream sent to the Island (at least in 7.0-7.02). The complete xBCML is recreated on any server event. Internally at SAP we have a prototype of delta handling of the xBCML that avoids this rebuilding of the Island if there is no inner data change, but development has not yet committed to implementing this feature yet (and if they do it is likely not to be available until NetWeaver 7.0 Enhancement Package 3).
