I'm no expert on Seam-Gen generated edit pages, but I think it goes like this : 

The edit pages edits a Widget called "widget", it doesn't matter if it is a new one, or an existing one.

You create a factory method for "widget" which in the same bean, injects the parameter widgetId. The factory method says "If I have an ID, load the widget, otherwise create a new one". Either way, it outjects a Widget called "widget", new or loaded.  

So, you load the edit page, which requests a bean called "widget" so seam calls the factory method on the bean, injecting the parameters beforehand. Your factory method checks the parameter, loads or creates a new widget, and returns it to Seam, which passes it to the page for editing.
