widgEditor submit problem

when I am using the widgEditor with model form so
<%= form_for @person do |f| %>
...
<%= f.text_area :content, :class=>'widgEditor' %>
...
<%= f.submit "Submit" %>

when I submit the form it does not work because it tries to submit to
non existing route like:

No route matches "/persons/2/css/widgContent.css" with {:method=>:get}

where /persons/2/ is the correct path but somehow it adds
/css/widgContents.css ???
Help!
cheers
