Don,
I tried to contact you through Skype. I don’t see how to fix this error, since I don’t know where it’s generated from:

Another significant release has been deployed today:
- Support for prototypes: ProtoDeclare, ProtoInterface/ProtoBody, ExternProtoDeclare, ProtoInstance.
- Further validation checks, making it hard for programmers to create a broken scene graph.
- Support for X3D, ClassicVRML and VRML97 file export (.x3d .x3dv .wrl)
- "Principle of least surprise" when null values are encountered from author (e.g. clear a field, etc.)
- Further unit tests in example program to confirm proper operation of correct and incorrect constructs.
- Internal package refactoring to improve inheritance, leaving exposed programming API unchanged.
- Performance looks great, despite complexity am unable to get execution time above "O seconds" - deserves profiling on large models.

A number of new data types have been added since X3D version 3.0, extra attention is needed to ensure that new classes and methods consistently support new specification additions. Method stubs need to be implemented (typically adapting source code from the Xj3D implementation).

When complete, this will be a big step forward for rigourously maintaining all X3D specifications, quality assurance tools and Web3D Consortium resources completely correct and in synch. I expect it will be especially helpful when we get to the stage of experimentation with X3D version 4.
