conditional layoutfile selection

I am working in a website which have different units. Each unit have an own layout. The urlManager have the rule


and this work fine. In the view file can i use $_GET[‘unit’].

I want to set the right view in the components/Controller.php like

public $layout=$_GET['unit'];

but it seems that the urlManager hast not jet be in action at this moment …

In an action-function i can do


, but i dont want to write this code in all actions.

How can I select the layoutfile early in the application depending of a value in the request (parsed by urlManager)?

Controller::beforeRender() seems to be a good candidate for this job.

thanks - this works fine
