Subject:      [JAVA3D] ClassCastException when removing a branchgroup
              containing Morph
              object
To: [EMAIL PROTECTED]

Hi All,

When trying to help a fellow lister who was receiving the following error, I
also get the error.  It occurs when you attempt to remove a live branch
group containing a morph object from the scene graph.  To illustrate the
example, I modified Sun's MorphApp example by adding the detach capability
to the branch group containing the morph object (line 167) and by calling
detach on the branch group (line 226).  The modified code is attached.

Here is the error:
java.lang.ClassCastException: javax.media.j3d.MorphRetained

        at javax.media.j3d.J3dThread.run(J3dThread.java:256)

This seems to be a bug.  Is it?

Evan
