Hi Lukas,

Thank you very much for the reply.

Yes, I see that Seaside is taking care of the values/names of the option
tags.  And, I do need to know which option was selected.  But, it seems to
me that only one name needs to be generated by Seaside for the select tag
so that the selected option (value part of option) can be returned.  It
seems the value attribute of option tags is being used by Seaside as a name
to return the selected option.

This may have more to do with what web browsers return than what Seaside
wants, I don't know?  I do realize that the options sent by Seaside don't
have to be Associations (although they match up nicely) and that may have a
lot to do with why Seaside always makes up values instead of sometimes
making them up and sometimes using the key of an Association.
