Now I figured that the Tableupdate is not successful, but it returns .T. nevertheless:

lcFieldState1 = GETFLDSTATE(-1,"MyView") && returns 111211
llSuccess = TABLEUPDATE(.F.,.T.,"MyView",laError) && returns .T.
lcFieldState2 = GETFLDSTATE(-1,"MyView") && returns 111211
*
IF NOT llSuccess
	*-- llSuccess = .T. so this does not fire.
	=AERROR(laError)
	=MESSAGEBOX(laError[2])
ENDIF
*
=REQUERY("MyView") && Error: Update conflict in cursor 'MyView'

This turns out to be a very difficult thing to solve.
