Hi Lewis,
It has been solved. But cannot remember what the exact solution. Image may be NSFW.
Clik here to view.
I think I deployed (all contents of) the solution again and it kind of worked.
How about NodeReferenceBinding?
Bind it with Root if screen is QA or OIF or FS.
Bind it with DataList if screen is OWL.
Sorry, cant remember exactly.
Regards,
Fred
