title: jqGrid - cannot populate select in search dialog - but ok in toolbar
body: <p>This doesn't seem to make sense, and unfortunately the one example on trirand seems to have the same bug</p>
  
  <p>with this column model</p>
  
  <pre><code>{name:'txtFixtureType', index:'txtFixtureType', width:110,
  stype: 'select',
  edittype:'select', editoptions: { 
  value: ":All;1:Division 1;2:Division 2"}},
  </code></pre>
  
  <p>Enabling a toolbar search results in a select for the column, with the values populated. However with the advanced search dialog the select appears, but contains no values.</p>
  
  <p>Is there some addition property that needs to be set?</p>
