Sean,
It could be the work on BranchGroup.compile(). Anyway, can you send
us a test program about finding ?
thanks,

> What happens when BranchGroup.addChild(null) is called?

> I was hoping to use the 'null' as a placeholder that I could replace later
with a call to setChild(), but the addition of 'null' to the BranchGroup child
list seems transient. Immediately after adding the right number of 'null's to a
BranchGroup (to get the number of children correct for replacement later), the
method numChildren() reports the correct number of children. However, when
numChildren() is later (in another method) called on this same BranchGroup, the
value returned is zero.
