title: Disable Field via Observer
body: <p>So I have my Observer.php in my custom module. From there I want to set the field "is_active" to be disabled. My problem is is that is_active is a default field so its all ready be added in Main.php. I'm needing something equivalent to <code>$model-&gt;setData</code> but instead more like <code>$model-&gt;setAttribut('is_active', 'disabled', true)</code>... I've been googling and googling and searching through the code and can't seem to find a solution. So if anyone has any thoughts that would be awesome. Thanks!</p>
