So how would you do it in "plain JSF" without the ViewController? In the contructor?
The constructor logic is going to get called on a postback as well as when a page is rendered, so you would need to distinguish the two cases. You also would not want to do the data setup if you're actually going to havigate to a different page instead. See my previous answer in this thread about using a phase listener. Bernhard Craig
