Well, it's a matter of making choices really. For Wicket it is a design
decission to make everything a component, and nest those components
hierarchical.
How about dynamic changing of component structure in runtime or at
least swapping components? Say, I have a large page, which in most
times will be the only page. Think a portal. I have a small login
component in it. No problem, I can define it in Page class.
But now I want to remove this login component after user logs in, and
to replace it with say, current promotions for registered users. Can I
do that? Or you recommend to consider my scenario as having two pages?
I would prefer to have one URL in the address bar ;)
Depends on what you prefer. You can use pages, which has the advantage
of clarity and previewability, or you could use panels and replace the
panels dynamically. As panels can contain any, including more nested
panels, you'll have all the flexibility you'll ever need. Replacing
versioned components can have a slight performance disadvantage to
creating page instances, as the replaced components will be recorded
using serialization to be able to roll back later. If you don't use
versioning, replacing panels is probably even cheaper than a page based
approach.
