I have one particular REEL that according to getNumChildren contains eleven children.
When I try to list the chidren, say using the supplied WireTap Python example listChildren.py, it will manage to list seven CLIP's but then fail on the eighth when trying to obtain node type with the message:
raise 'Unable to obtain node type: %s.' % child.lastError()
Unable to obtain node type: The given ID is not valid. The ID must begin with the root node of the host. The root node may be queried through the call getRootNode.
Is perhaps what I'm seeing the result of a corrupt clip?
