Aaaah. I still have a problem. I can't seem to use components in my
sub-classed component. For example, if I have the following:
class RedComponent extends ColorComponent
{
var $components = array('Session', 'Flickr');
...
}
I get the folloiwng error when I reference the component from
RedComponent, either as $this->Flickr, or $this->controller->Flickr.
Notice (8): Undefined property: RedComponent::$Flickr [APP
\controllers\components\red.php, line 30]
If I define the component in the ColorComponent class, then I can
reference it using $this->controller->Flickr, but NOT $this->Flickr.
what am I doing wrong???
