Stefan,
The shortcut callMixins() has issues with the Zend Platform. So use the
more verbose syntax:
public function __call($method, $arguments)
{
if (!$callable = sfMixer::getCallable('sfController:'.$method))
{
throw new sfException(sprintf('Call to undefined method
Track::%s.', $method));
}
array_unshift($arguments, $this);
return call_user_func_array($callable, $arguments);
}
