i'm not sure what's missing from your code, but since the  
SamplexMember _is_ showing up, i'd say to take a good look at the way  
that Samplex is handling it, and look for any differences.  you might  
consider modeling your custom member class after SamplexMember rather  
than the one in the older wiki page.

USE_SCHEMA_EDITOR is a global setting, not one that you'd turn on  
just for your type.  i have no idea what errors you're seeing,  
though... it would help if you could file a bug report w/ a complete  
description of the exact steps that you took and a full traceback.
