It will not ignore ViewPlatforms specific activation radius.
>From Behavior:
* The scheduling region defines a spatial volume that serves to
* enable the scheduling of Behavior nodes. A Behavior node is active
* (can receive stimuli) whenever a ViewPlatform's activation volume intersects a
* Behavior object's scheduling region. Only active behaviors can receive stimuli.
If the above condition satisfies and the Region specified in the
constructor of wakeupOnViewPlatformEntry() intersect with
ViewPlatform's activatin volume then it is trigger.

Yes, if ViewPlatforms is in the scene graph then behavior will
search for it to see if above conditions satifies. Whether there
is a View attach to viewplatform did not matter.
