Arbit - project tracking

If I try to access an object attribute through the magic method __get($attribute), dwoo gets the value but I can't use it in if blocks or other functions:

For example, I have this class:
<pre>
class testClass
{
  protected $_id;

  public function __set($attribute, $value)
  {
    $method = 'set' . ucfirst($attribute);
    if (method_exists($this, $method)) {      
      $this->$method($value);      
    }
  }

  public function __get($attribute)
  {
    $method = 'get' . ucfirst($attribute);
    if (method_exists($this, $method)) {
      return $this->$method();
    }
  }
  
  public function getId()
  {
    return $this->_id;
  }

  public function setId($id)
  {
    $this->_id = $id;
    return $this;
  }
}
</pre>

I create an instance and assign it an id:
<pre>
$test = new testClass();
$test->id = 4; // For example, 4
$data = array('test' => $test);
</pre>
Then I render the template:
<pre>
$dwoo = new Dwoo();
$dwoo->output('testTemplate.phtml', $data);
</pre>
The template 'testTemplate.phtml' is:
<pre>
{$test->id}
{intval($test->id)}
{if $test->id == 4} correct! {else} bug! {/if}

{$test->getId()}
{intval($test->getId())}
{if $test->getId() == 4} correct! {else} bug {/if}
</pre>


Expected result is:
<pre>
4
4
correct!

4
4
correct!
</pre>
However, the result I get is:
<pre>
4
0
bug!

4
4
correct!
</pre>
