My program build some scene using internal
buildScene().
Group objRoot = buildScene();
objRoot.setCapability(Group.ALLOW_CHILDREN_READ);
objRoot.setCapability(Group.ALLOW_CHILDREN_WRITE);
objRoot.setCapability(Group.ALLOW_CHILDREN_EXTEND);
..
..
root.addChild(scene); // root is BranchGroup
..
..
Then, the scene is displayed. There is a button that
add box into 'objRoot', but it occurs error.
[error]
--------- UNCAUGHT EXCEPTION ---------
javax.media.j3d.RestrictedAccessException: Group: only
a BranchGroup node may be added
at javax.media.j3d.Group.addChild(Group.java:255)
>>>>>>>>
How can I add some node into 'objRoot' in run time
after the initial scene is built?
Thanks in advance.
