title: Populate date in MultiOptions element of Zend Form
body: <p>Hello I have an array like this :</p>
  
  <pre><code>Array ( 
    [id] =&gt; 1 
    [code] =&gt; Dep98 
    [description] =&gt; Hello World 
    [facility] =&gt; Array ( 
      [0] =&gt; FacName1 
      [1] =&gt; FacName2
    )
  )
  </code></pre>
  
  <p>But when I populate this array to Zend_Form it only show data in textboxes elements having same id as defined in array index not in multiselect dropdown element. for example:</p>
  
  <pre>
  'code'        id is also define in form's first textbox element,
  'description' id is also define in form's second textbox element,
  'facility'    id is also define in form's third MultiOptions element
  </pre>
  
  <p>But in MultiOptions it does not show any record.</p>
