I'm trying to fill a simple select box using templates but I have a 
problem when I try to set the selected value. Here is my code:


    def render_selectauthor(self, ctx, data):
        author = data.firstname + " " + data.lastname
        if data.id == self.idauthor:
            ctx.fillSlots("authorselected", "selected")
            ctx.fillSlots("authorselected", None)
        ctx.fillSlots("authorvalue", data.id)
        ctx.fillSlots("authorlabel", author)
        return ctx.tag


     <select name="idauthor" nevow:data="selectusers" 
          <option nevow:pattern="item" nevow:render="selectauthor">
              <nevow:attr name="value"><nevow:slot name="authorvalue" 
              <nevow:attr name="selected"><nevow:slot 
name="authorselected" /></nevow:attr>
              <nevow:slot name="authorlabel">select...</nevow:slot>

The problem is that the attribute selected allways appear in my html 
code, and then allways the last item is the selected.
Can anybody tell me how to fix this problem? If possible don't use a 
attribute even when I have set this one in my template?

Thank you very much.
