Note also that we need a way to disambiguate between the highlighted
HAnimHumanoid fields in XML (they have the same type of children nodes, so
setFieldOverride() is necessary (I need to double check the X3DJSAIL output
of X3dToJava.xslt programs). If you want to make addJoints(), addSite(),
addSkeleton() and addViewpoints() actually call setFieldOverride(), that
would be something. You actually have to look at the XML output from Java
to see the issue. Apparently, you haven't validated the XML output from
Java? Again, you can't see the problem by looking at the archive, the
problem is not in the archive.
I will continue investigating with a new X3DJSAIL, I recently did an svn
update.
