[x3d-public] This may be a duplicate bug report for X3DJSAIL, but this time, I am sending an X3D file.

[John Carlson]

If there’s a bug in my example, please provide better reporting than Null pointer exception, if possible.  There may be a configuration property I need to set as well.

Thanks,

I will look into this soon, to see if I can derive a solution. SYS. I am too tired to see a solution right now. My brain isn’t working, but it looks like a configuration property vital to debugging may not be set. It would be good to know which one in an error message. It’s kinda your call Don, unless I need to improve my Java code (which is perfect, obviously 😊.

I think we’ve covered this before, actually.   Sigh

Note that code generated from X3dToJava.xslt produces the same error. I am including both.
