If you have a test case, we can look into it. It sounds like a bug.

>You can select a predefined polyhedron to be displayed in a scene (cube, or
>tetrahedron, etc).
>
>For any polyhedron, you can display ("turn on/off") the polyhedron's
>1) Vertex spheres
>2) edges as lines
>3) edges as cylinders
>4) faces as planes.
>
>I accomplish this by defining a Switch node and attaching a BranchGroup for
>each of the 4 cases listed above. (These BranchGroups contains the geometry
>Shape definitions.)
>
>You can also combine two or more polyhedra together to define what I call a
>"combined object".
>
>To accomplish this, I define a new scene object (BranchGroup)"BG2" and
>attach it to the live scene graph "BG1". Then I detach the Switch node for
>a polyhedron from "BG1" and attach it to "BG2".
>
>The Problem: When I do this, the polyhedron displays all 4 features list
>above, *even when the Switch bits have not been set* to display all 4
>features.
>
>For example, if only (3) above it set to be displayed, so the polyhedron
>only displays as cylinder edges, then I detach it from BG1 and add it to
>BG2, the polyhedron will be displayed with vertex spheres, and face planes
>showing in addition to the cylinder edges.
>
>I print out the Switch bit right after the I add it to BG2,
>System.out.println("BS: "+theLastSO.SNPropertiesBS);
>and it shows only one bit set (3), yet all 4 features are actually being
>displayed.
>
>I even reset the Switch bit after detach and re-attach
>theLastSO.SNProperties.setChildMask(theLastSO.SNPropertiesBS);
>yet the polyhedron still is displayed with all 4 features showing.
>
>I don't recall having this problem before I started using Beta 2.
>
>Anyone else seeing a problem when a Switch is detached from a BranchGroup
>and then added to another BranchGroup?
>
>(Actually, I have a BranchGroup just above the Switch and it is this BG I am
>detaching and re-attaching, but I thought another BG would make the
>description too confusing to follow.)
