Im trying to create a customized version of admin_double_list where each
option tag get a style attribute setting the background image to a
thumbnail. Ive got it displaying the thumbnails just fine, but for some
reason it will not save the addition to the database. Ive essentially copied
2 methods, object_admin_double_list and options_for_select to a new helper
which is called in a customized theme. I havent tweaked anything about those
functions other than adding some paramters and an extra block of logic. I
haavent removed any logic or adjusted anything beyond adding the extra
params and code block. Furthermore the code on the rendered page is
identical to that of a generic admin_double_list (at least as far as I can
see). Also note I havent added/changed any class or id attributes on any of
the elements.
Im sure it must be something simple im overlooking but ill be damned if I
find it.
