Examples of AjaxFallbackLink

org.apache.wicket.ajax.markup.html.AjaxFallbackLink
An ajax link that will degrade to a normal request if ajax is not available or javascript is disabled.
If JavaScript is enabled then the registered JavaScript event 'click' handler will be used, otherwise the 'href' attribute if the markup element is an <a>, <area> or <link>. AjaxFallbackLink doesn't fallback if the markup element is none of the three above.
