I have a simple User form with a simple Usercontroller.
The 'edit' action looks like:
  def edit
    @user = current_user

In the view:
<% form_for(@user) do |f| %>
blah blah
<% end %>

What it generates is:
  <form action="/user.%23%3Cuser:0x34a498c%3E" class="edit_user"
id="edit_user_196" method="post">
  <div style="margin:0;padding:0"><input name="_method" type="hidden"
value="put" />
  <input class="inline" id="user_login" name="user[login]" size="30"
type="text" />.
  <input src="/images/buttons/registreren.png?1239978560"
type="image" />

How does that form 'action' field becomes so b0rked?

Running Rails 2.3.2

Is user an active record object ?

That was my initial hunch as well. And it is an AR object.

I believe that the fact that the user is a singleton resource matters.
    map.resouce :user, :controller => "Users"

I modified the form_for and passed an explicit path with :url =>
user_path. This seems to work. But it is vert strange Rails doesn't
pick this up automatically. Then again maybe I'm defining the resource

You misspelled "resource" here.  Is it also misspelled in your actual
code?  If so, that could be the problem...

Ow I did misspelled it. I didn't do so in my code.

Just make users a collection (map.resources :users), then everything
will work fine. Or if your really want it to be a singleton (bad idea,
not restfull if you have more than 1 user in your app), then use
form_for :user, :object => @user.

Thank you Dmitry.
I'll ponder a bit on your remark, my initial gut feeling is that I do
want a singleton resource as I never want to expose more than 1 user.
Ever. Which is restful. But I'll think about it.

Most time, you can put a reference manual in your desk.
When you can't confirm the settings , you can find it very quickly.
For example :
