the error means that the NodePtr you pass to IntersectAction::apply() is
not pointing to a node (i.e. it is NullFC).
In the original 13ClusterClient.cpp scene is variable local to main; did
you add a global variable named scene and not remove the local one from
main ?
Other than that I can only suggest you investigate where scene is being
set, perhaps examining the program run in a debugger.
Hope it helps,
Carsten
