I had an old code which uses ShopComponent. In that code Shop Category could be retrieve as Components publi property: Yii::app()->shop->category.
However, now code is refactored and there is no more shop component. All code is under public & view folders, wihtout Shop Component (do not ask why, it is simply so ).
So as I am quite new to Yii, I wonder what is the way to save some public / global parameter somewhere? It is not just a string varaible, it is an object - model (Category).
