title: Select prompt option disappears when validation fails in Rails
body: <p>Let me preface by saying I'm a noob to Rails and StackOverflow so please go easy on me.  I'm using Rails 2.3.8 with sqlite3 on my dev box.</p>
  
  <p>I have created a select pulldown in a form using the following:</p>
  
  <pre><code>&lt;%= select( "communication", "gig_id", { "Add New Gig" =&gt; "new"}, {:prompt =&gt; "-- Select Gig --"}, :onchange =&gt; "toggle(this, 'gigInfo')") %&gt;
  </code></pre>
  
  <p>However, when something else in the form fails validation and the "new" page is re-rendered, my prompt goes away and the only option left is the "Add New Gig" option.  This is the case with ALL my forms and I can't seem to find any answer as to why.</p>
  
  <p>My controller uses the basic scaffolding so I'm sort of at a loss.  Any help would be greatly appreciated.</p>
