Note

  • alloy:link is intended to be used to render a hyperlink that navigates to other JSF views via HTTP GET, or perhaps to re-render the same view with different view parameters via f:param child tags.
  • alloy:outputLink is intended to be used to render a simple <a href="...">hyperlink</a> that requests a URL via HTTP GET.

alloy:link

Link is a UIOutcomeTarget component that renders an <a> element (hyperlink). Since it extends HtmlLink, it supports all the features of h:link.

Navigation Usage

The component can be used to navigate between pages with the outcome attribute. Setting includeViewParams=true will automatically include all of the f:viewParam tags (view parameters) as URL parameters.
To Param page 
foo=
