[Seaside] Auto-create accessors preference causes infinite loop in components

[Yar Hwee Boon]

Seems that if the auto create accessor preference is turned on, a DNU for  
a possible accessor in components (just an observation, I tried with a  
couple of component subclasses) will causes some sort of infinite loop. To  
reproduce, just implement:

==============
#renderContentOn: html
	Transcript cr; show: 'x'; cr.
	WAFormDialog new validationError
==============
