com.sun.rave.web.ui.renderer.HyperlinkRenderer
public class HyperlinkRenderer
This class is responsible for rendering the Hyperlink
component for the
HTML Render Kit.
The Hyperlink
component can be used as an anchor, a
plain hyperlink or a hyperlink that submits the form depending on how the
properites are filled out for the component

public void decode(javax.faces.context.FacesContext context, javax.faces.component.UIComponent component)
Decode will determine if this component was the one that submitted the form. It determines this by looking for the hidden field with the link's name appended with an "_submittedField" If this hidden field contains the id of the component then this component submitted the form.
