This may or may not be the same problem, but I've been having difficulties
with some PROTOs whereby the parser tells me a particular field does not
exist when it clearly does. In these cases I find that DEFining the
offending node gets the file through the parser and everything works fine.
http://www-lce.eng.cam.ac.uk/~jpw20/Door.wrl demonstrates the problem; most
(if not all) of the DEFs are not needed, but without them, although the file
still renders correctly, events are not routed correctly (so that, for
example, it's not possible to have a open door using this PROTO without the
DEFs).

Hope this helps,
