title: using default value in g:select tag in grails
body: <p>I am using g:select tag like this</p>
  
  <pre><code>&lt;g:select id="ua_selectedResource" style="width:100px;font-size: 9px"  from='${resourcesList}' value="" optionKey="id" optionValue="resourceName"  noSelection="['null':'Select a Resource']"&gt;
  &lt;/g:select&gt;
  </code></pre>
  
  <p>resourceList is a list of resource objects (with fields id, resourcename...etc), I want the default selected value to be the resource which has id '1' . How do I set that condition in the value attribute?</p>
