[x3d-public] getting a NullPointerException in X3DJSAIL

[John Carlson]

  In getType() in fieldValueObject.java:

At this line:

X3DConcreteElement correspondingPrototype = findAncestorSceneObject().findElementByNameValue(prototypeName);

(there’s another one too, in my patches).  Attached is the code which exercises this case.
