title: using the maxlength option in cakephp - but it outputs two maxlength values in the html
body: <p>I'm just messing about trying to figure out cakephp which looks like it's going to be a lot of fun.</p>
  
  <p>I have a form input which goes like:</p>
  
  <pre><code>echo $form-&gt;input('Campaign.title', array('maxLength'=&gt;'76px'));
  </code></pre>
  
  <p>which outputs:</p>
  
  <pre><code>&lt;label for="CampaignTitle"&gt;Title&lt;/label&gt;&lt;input name="data[Campaign][title]" type="text" maxLength="76px" maxlength="255" id="CampaignTitle" /&gt;
  </code></pre>
  
  <p>notice the two values for the maxlegth. How can I get rid of the second "255" value which seems to be preferred in IE.</p>
