title: how to set up a zend multiCheckbox form field with the checkboxes checked?
body: <p>i have this form:</p>
  
  <pre><code>$this-&gt;addElement ( 
              'multiCheckbox', 'servers2', 
              array (
                     'checkedValue' =&gt; '0',
                     'multiOptions' =&gt; array(
                          '11.com' =&gt; '.com',
                          '12.com' =&gt; '12.com',
                          '16.com' =&gt; '16.com',
                          '3.com' =&gt; '17.com'
                          )
              ));
  </code></pre>
  
  <p>the problem is that the <code>checkedValue</code> doesn't work for this setup, it does for a simple checkbox. I've also tried <code>'checkedValues' =&gt; array('1','0')</code>, singular or plural, 
  but no end in sight.</p>
  
  <p>any ideas?</p>
  
  <p>THanks</p>
