All Implemented Interfaces:

java.util.EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.ValueHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder

public class Param
extends javax.faces.component.UIParameter
implements javax.faces.component.ValueHolder

Param is a component that extends the standard UIParameter to implement ValueHolder and thus support a Converter to convert the supplied value to string, if necessary.

You can use it the same way as <f:param>, you only need to change f: into o: to get the extra support for a Converter by usual means via the converter attribute of the tag, or the nested <f:converter> tag, or just automatically if a converter is already registered for the target class.
