Rails - Oct 2006 - Help needed - Observe_form , passing parameters but ...

I think after 3 days I"m getting closer to getting my observe_form to work.
At least now it''s rendering the partial , only with a nomethod (nil)
error.
Here is the problem -> I don''t think I know how to grab the params
correctly
off the form.

Here is the form -
<div id="parta">
<form id="asearch">
<fieldset><legend>Category</legend>
<select name=position[category_id][] size = "4" multiple =
"multiple" id
''cat''><%options_from_collection_for_select @categories,
:id, :name
%></select></fieldset>

<fieldset><legend>State</legend>
<select name=position[state_id][] size = "4" multiple =
"multiple" id
''stat''><%options_from_collection_for_select @states,
:id, :name
%></select></fieldset>

<fieldset><legend>Terms</legend>
<select name=position[term_id][] size = "4" multiple =
"multiple" id
''term''><%options_from_collection_for_select @terms, :id,
:name %></select></fieldset>


<fieldset><legend>Title</legend>
<input type="text" id="title"
name="position[title]" size="10" id =
''title''
/></fieldset>

<fieldset><legend>City</legend>
<input type="text" id="city"
name="position[city]" size="10" id =
''city''
/></fieldset>

</form>
</div>

<%= image_tag("roller.gif",
               :align => ''center'',
               :border => 0,
               :id => "roller",
               :style => "display: none;") %>

<%= observe_form "asearch",
                  :frequency => 0.5,
                  :update => ''table'',
                  :before =>
"Element.show(''roller'')",
                  :success =>
"Element.hide(''roller'')",
                  :url => ''list'',
                  :with => "asearch" %>

<div id="partb">
<div id="table">
<%= render :partial => "positions_list", :layout => false 
%>
</div>
</div>

From the server log , the parameters being sent -
  Parameters: {"asearch"=>"position[state_id][]=35",
"action"=>"list",
"controller"=>"ajaxsearch",
"position"=>{"city"=>"Boston",
"title"=>"",
"term_id"=>["3"]}}

So the user can pick any number of choices in any number of elements

One thing that looks weird in the parameters above is -
"asearch"=>"position[state_id][]=35" as opposed to
"position"=>{"city"=>"Boston" and
"term_id"=>["3"]}

anyway since the label names are position[field] in the controller I did a

@positions = Position.new(params[:position])

Yes as I said above getting a nil error on the finds.

Anyone ?
