Node Lookup which worked in 1.1 release does not work in 1.2 release.
Identified when a customNode Id is used from with another CustomNode inside the main Scene content.

If CustomNodes are inserted dynamically they can be 'lookup'ed otherwise not

This may be a valid decison now for 1.2 but it would be nice to know and the wording of the 1.2 API should be changed
