E_STRICT error in gridview

gistfile1.aw

I have a CGridview, with a column that calls a function in the model. 
    $data->getActieveKanalen($data->id, '.$kanaal->id.', $row)

Today, I turned E_STRICT on, and I got the following PHP error. Before I never saw this, because only E_ALL was on. With only E_ALL, the code works without any problems..




PHP Error

Non-static method CController::createUrl() should not be called statically, assuming $this from incompatible context

/data/ksa/apps/jeroen/ics/protected/models/Incident.php(319)


315         
316         if(isset($var))
317             return '<div  style="text-align:center"><a class="kanaalToggle" id="k-'. $kanaal_id .'-'. $this->id .'" kanaal_id="'. $kanaal_id .'" href="'. CController::createUrl('/kanaal/toggle', array('id'=>$kanaal_id, 'iid'=>$this->id)) .'"><img src="'. Yii::app()->request->baseUrl .'/images/kanaal/onicon.JPG" alt="Deactivate"/></a></div>';
318         else
319             return '<div  style="text-align:center"><a class="kanaalToggle" id="k-'. $kanaal_id .'-'. $this->id .'" kanaal_id="'. $kanaal_id .'" href="'. CController::createUrl('/kanaal/toggle', array('id'=>$kanaal_id, 'iid'=>$this->id)) .'"><img src="'. Yii::app()->request->baseUrl .'/images/kanaal/officon.JPG" alt="Activate"/></a></div>';
320     }    //return '<a class="kanaalToggle" id="k-'. $kanaal_id .'-'. $this->id .'" kanaal_id="'. $kanaal_id .'" incident_id="'. $this->id .'"
321     
322     
323     
324 }

I faced the same problem and fixed by looking into application log. there I found the exact line number.
