Fatal error: Call to a member function trigger() on a non-object in .../model.php on line 2106 when running as CakeTestCase

I'm a newbie to PHP, CakePHP, and the CakePHP unit testing framework for 1.3.

I created a simple test case of a model and ran into this error:

Fatal error: Call to a member function trigger() on a non-object in /Users/calvinc/Sites/lhasa/web/cake/libs/model/model.php on line 2106

I notice that the line 2106 in model.php is as follows:

  if ($query['callbacks'] === true || $query['callbacks'] === 'before') {
      $return = $this->Behaviors->trigger($this, 'beforeFind', array($query), array(

I'm guessing that Behaviors is not setup. What would be the cause of that?

Here's the dump of the Login object.

I think that your problem ... is my problem. So .. my problem was that I had a method inside of my model with the same name of my model.

class Ranking extends AppModel {
   function ranking($a)....
}

This was making the PHP interpret the function as constructor, so the AppModel constructor was not being called. And our model did have not the data correctly.
