First off I agree with @jbrookovers suggestion.

However, If you do actually want the hole page to refresh, Why not create a new class RefreshingBasePage? Then just move your <meta refresh....> to the new classes .html file. Just insert the refresh into the head via a <wicket:head></wicket:head> element.

Then you can leave your other pages free to inherit from BasePage without the refresh getting in the way.

When you have a 

public class BasePage extends Page

and then another

public class SubPage extends BasePage

you don't actually get them as separate pieces. This method of class (and markup) extending only exists to make the process more "object" and "java" like. In the end, the entire page hierarchy is combined together to a single, rendered page.

Now, if you want one sub-part of the page to refresh, I suggest creating a Panel and adding an AjaxSelfUpdatingTimerBehavior to that component. This will let you auto refresh any part (or multiple parts) of a page without the entire thing re-rendering.
