[JAVA3D] GetNamed

[kwc]

hi,   I'm trying to use the getNamedObjects call thats been noted in the mail archive as usable to get references to nodes in a scene.  The particular case is using the vrml97 jar and a HANIM vrml file.   I'm working with a modified version of the Simple example from the VRML examples.  It seems to work fine with a simple vrml file ( a cube for instance) but the HANIM file causes the exception given below.   Can anyone comment/hazard a guess at a cause?   Thanks.   kwc ____________________________ before scene.getNamedObjects java.lang.NullPointerException     at javax.media.j3d.LinkRetained.setSharedGroup(LinkRetained.java:46)     at javax.media.j3d.LinkRetained.clone(LinkRetained.java:216)     at javax.media.j3d.Link.duplicateNode(Link.java:185)     at javax.media.j3d.Link.cloneNode(Link.java:109)     at javax.media.j3d.Leaf.cloneTree(Leaf.java:58)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Group.cloneTree(Group.java:361)     at javax.media.j3d.Node.cloneTree(Node.java:378)     at com.sun.j3d.loaders.vrml97.impl.NonSharedNode.getImplNode(NonSharedNode.java:126)     at com.sun.j3d.loaders.vrml97.impl.ProtoInstance.getImplNode(ProtoInstance.java:145)     at vrml.BaseNode.getImplNode(BaseNode.java:52)     at com.sun.j3d.loaders.vrml97.VrmlScene.getNamedObjects(VrmlScene.java:173)     at SimpleVrml97Viewer.gotoLocation(SimpleVrml97Viewer.java:166)     at SimpleVrml97Viewer.<init>(SimpleVrml97Viewer.java:121)     at SimpleVrml97Viewer.main(SimpleVrml97Viewer.java:321)     at symantec.tools.debug.Agent.runMain(Native Method)     at symantec.tools.debug.MainThread.run(Agent.java:48)
