How to update UI from backend

Hi all,

I would like to implement a WebDynpro-UI which should be updated automatically by some backend-process. No user-interaction should be neccessary. Is there any possibilty to realize such a scenario?

Thanks for each hint,

Christoph

    Hi,

    Which UI you need to be updated..

    Place this background process in one method , and call it in wdDoInit() method.

    So it'll get updated when init methos is called..

    Remember for a view, wdDoinit() method called only once for a Roundtrip.

    Regards

      Hi,

      To get data into WebDynpro UI from backend, we need to call.

      Declare a method in ComponentController which calls the background process..

      If you keep the method call in ComponentController, we can share this method

      among other views..

      wdThis.wdGet<Component ControllerName>Controller().<methodName>

      Regarrds

    If available in your release, you could use the MessageBasedTrigger UI element. Or if polling is an option, you can use TimedTrigger.
