Java3D - picking

[seatizen]

Hello.
My problem is:
I've got two Box objects on the screen. I click one of them (picking):
....
sceneGraphPath = branchGroup.pickClosest(pickRay)
....

How can i find out (using the sceneGraphPath object) which Box did i
clicked?
When i was using ColorCube objects i could do it:
ColorCube cc = (ColorCube)sceneGraphPath.getObject();
and it worked. Now i need to use Box objects and there is an error
(ClassCastException).
Is it possible that pickClosest's result is only one of the sides of the Box
(not whole Box)? - and if so - how can i find out which Box object is it
exactly??
I'll be REALLY greatful for any help.

PS: If you have some basic code (about picking) please send me too.
And sorry

Are the Box objects the lowest level nodes? Are they pickable? Are there
other pickable nodes? What is the class of the object being returned? You
can use .getClass ().getName () to find out. It's possible that it's just
an unexpected object in the scene graph because pickClosest will find an
object--and your intuition may be right that a component of Box is being
picked.

There are only two Boxes, so it's rather impossible, that i picked another
object. I'm really "fresh" Java user, so i'm not sure if i understand your
question properly. But let's try
Simplified scheme:
Box2
|
BG-->TG1-->TG2-->Box1

What did you mean asking if they were pickable? (when i used ColorCube i had
no problem, and now i changed only ColorCubes for Boxes).
The class of returned object is Shape3D (shouldn't it be just Box?).

stuck with the same problem

Hey mate, did u get any solution for that,
I am building a java3d GUI, using which users can create custom scene graphs, without needing to know the code, i want to pick specific boxes using mouse, and i want to be able to move them around.. so for that i need picking..
let me know if u get the answer
cheers, m also lookin into it. !!
