    Do you know what 'e' actually is?  It is quite common
for the first child of the document element to be a
TextNode (white space between elements) or any of 'defs', 'style',
'title', 'desc', 'script', ....

    None of which have a GraphicsNode since they don't draw anything.

    Also was the document loaded with the document state set to
ALWAYS_DYNAMIC or ALWAYS_INTERACTIVE?  If it wasn't then the
BridgeContext doesn't bother to build the element/GraphicsNode
mapping.

    HTH
