I'm using CA builder from Form's dataenvironment.

Do I first have to modify above builder to use new Cursoradapter class based on Cursoradapter base class?

Replacing AutoOpen method:

*** Setup code: DO NOT REMOVE
if not pemstatus(This, '__VFPSetup', 5)
	This.AddProperty('__VFPSetup', 1)
	This.Init()
endif
*** End of Setup code: DO NOT REMOVE

with the next

DEFINE CLASS EmptyCA AS CursorAdapter
	FUNCTION AutoOpen()
		NODEFAULT
		RETURN this.CursorFill(.F.,.T.)
	ENDFUNC
ENDDEFINE

I think that at least This.Init() shoud be added too.
