form_for("item[subobject]", @item) do |f|
f.radio_button("title", "matchval")
end
This would produce a radio button with an ID="item[subobject]_title", which is invalid because IDs can't include bracket characters. All other form_helpers already fixed this issue using the "sanitize_name" function, but this one omitted to use it.
I provide a patch with a unit test case and a fix in this ticket: http://dev.rubyonrails.org/ticket/11298
The dev.rubyonrails.org says for my patch to get integrated I should post here asking people to mark my ticket +1.
So I'm posting!
