    • onInitialize

      protected void onInitialize()
      Description copied from class: Component
      This method is meant to be used as an alternative to initialize components. Usually the component's constructor is used for this task, but sometimes a component cannot be initialized in isolation, it may need to access its parent component or its markup in order to fully initialize. This method is invoked once per component's lifecycle when a path exists from this component to the Page thus providing the component with an atomic callback when the component's environment is built out.

      Overrides must call super#Component.onInitialize(). Usually this should be the first thing an override does, much like a constructor.

      Parent containers are guaranteed to be initialized before their children

      It is safe to use Component.getPage() in this method

      NOTE:The timing of this call is not precise, the contract is that it is called sometime before Component.onBeforeRender().

      Overrides:
      onInitialize in class Page

    • onBeforeRender

      protected void onBeforeRender()
      Description copied from class: Component
      Called on all visible components before any component is rendered.

      NOTE: If you override this, you *must* call super.onBeforeRender() within your implementation. Because this method is responsible for cascading Component.onBeforeRender() call to its children it is strongly recommended that super call is made at the end of the override.

      Changes to the component tree can be made only before calling super.onBeforeRender().
      Overrides:
      onBeforeRender in class Page
