[openvrml-develop] .wrl file problem in openvrml 0.16.6,

[stone <12s...@16...>]

Hi All!
I am using ARToolKit Pro v4.3 with OpenVRML 0.16.6 in windows.
I loaded a .wrl file in OpenVRML 0.14.3,it's OK.But when I was loading the .wrl file in this OpenVRML 0.16.6,it showed an error:"chahu.wrl:546:44:node "Teapot01" has not been defined in this scope ",I don't known what's wrong with this.
The addition is the .wrl file which was exported by 3d max 9.
I am first use OpenVRML,please nice one help me,thanks very much.

In the .wrl file,
#VRML V2.0 utf8
# Produced by 3D Studio MAX VRML97 exporter, Version 9, Revision 1
# Date: Fri Oct 22 17:40:01 2010
DEF Teapot01 Transform {
  translation 0.05427 0 0.2242
  children [
  DEF Teapot01-TIMER TimeSensor { loop TRUE cycleInterval 3.333 },
  DEF Teapot01-ROT-INTERP OrientationInterpolator {
......
 
ROUTE Teapot01-TIMER.fraction_changed TO Teapot01-ROT-INTERP.set_fraction
ROUTE Teapot01-ROT-INTERP.value_changed TO Teapot01.set_rotation
}
Error is the last line :ROUTE Teapot01-ROT-INTERP.value_changed TO Teapot01.set_rotation
The .wrl file is exported by 3d max 9.

The problem is that OpenVRML 0.16.x's parser doesn't make the DEF name
available for usage in a ROUTE until the end of the node body.  In your
file, the problem ROUTE occurs inside the body of the node Teapot01.

I tried your file in trunk OpenVRML and it works there.  I suspect this
got fixed in 0.17.0 when the Antlr-based parser was replaced with the
current Spirit-based one.

Thanks very much.I'm trying to compile other OpenVRML into this  ARToolKit . but if I want to use OpenVRML0.16.6,I would use which tool to export my .wrl file with cartoon.
