By default fields that are invalid are wrapped in:
<divclass="fieldWithErrors"><inputtype="text"name="blah"></div>
To override and wrap in spans instead of divs place the following in your environment.rb:
ActionView::Base.field_error_proc=Proc.new{|html_tag,instance|"<span class=\"fieldWithErrors\">#{html_tag}</span>"}
or to not use wrapping at all:
ActionView::Base.field_error_proc=Proc.new{|html_tag,instance|"#{html_tag}"}
