title: codeigniter core/model.php undefined property
body: <p>I have never touched the model.php file, however I am getting this error. Jobprocess is my controller and <code>$lastname</code> is a variable assigned correctly within it. I have no idea why this error is coming up.  This is using codeigniter framework</p>
  
  <pre><code>Message: Undefined property: Jobprocess::$lastname
