[x3d-public] X3DJSAIL: ProtoInstance fieldValue not an MFNode, but an SFNode.Complains!

[John Carlson]

I don’t see as fieldValueList in ProtoInstanceObject can ever be null, (It can have 0 elements), so the hasFieldValue() test will always return true, even if the ProtoInstance has 0 children.  Please correct me if I am wrong.

Sorry for delay, didn't understand earlier...

The exception reports that ProtoInstance USE='G1' is not allowed to have any contained fieldValue.  USE nodes can only have a containerField attribute, no children, nothing else.

That said, not seeing what line in your source code caused the exception.
