I'm trying to detect a change to the primaryVisibility of a node.
Pre-2009 change handlers are doing nothing for either $Object nor $Object.baseObject
And 2009's Node Event System seems to happily ignore it as well.
What obvious thing am I missing?
( a timer that continually checks is not an option - and, sadly, a controller that would change the setting is not an option either as any changes made to .primaryVisibility after #preRender get happily ignored until the next frame; which does no good for the current frame. )
