Implementing a Renderer Class

• Object getConvertedValue(FacesContext context, UIComponent component,
                           Object submittedValue)

  • Necessary because external renderers must do the conversion work of their components
  • Could use code in UIInput if it were public (but it's not due to an oversight)
  • Can use replicated code provided in com.corejsf.util.Renderers

• boolean getRendersChildren()

  • Specifies whether a renderer is responsible for rendering its component's children
  • If false (the default), encodeChildren not called

• String convertClientId(FacesContext context, String clientId)

  • Override only if client restricts ID format (for example disallows special characters)
