    • addVerifyCallback

      void addVerifyCallback(Runnable callback)
      Adds a verify callback, which is allowed while the page is loading. Such callbacks are invoked once, after the page has been loaded successfully, and are then discarded. This was added specifically to ensure that components only verify that required parameters are bound after all components and mixins of the page have had a chance to initialize.
      Parameters:
      callback - to be invoked after page loaded

    • addResetCallback

      void addResetCallback(Runnable callback)
      A reset occurs when a request for a page arrives that did not originate on the same page. This gives the application a chance to reset the state of the page.
      Parameters:
      callback - invoked when a page is activated by link from some other page.
