[Html-widget] Bug on select options(undef)?

[Ted Carnahan]

We've found an inconvenient bit of behavior, but we're not quite sure 
how to handle it.  On Selects, using attribute chaining, if you 
(inadvertantly) set options to undef, then the object returned out of 
Class::Accessor::Chained::Fast is the value of the options field 
(undef), instead of the reference to the element.  That seems like 
useful behavior in general (passing undef is like not passing any 
options, so you would want it to return the current value), but is 
supremely annoying in this case (we end up putting our calls to options 
last in the list so that they can't muck anything up).  Any ideas?
