    GateIn 3.1 and Vaadin 6.7.3

    joseph bijop Newbie

      Hello,

       

      please accept my apologise if it not the right place...

       

      I would like to use Vaadin framework my portlet project deployed under GateIn but I'm facing a big refreshing problem : the first time the portlet is installed or the first time the portal is started, everything is fine : the portlet is working. But if I change portlet window mode, or portal page layout, its contents is not painted anymore, showing an undefined progress indicator for ever !!!, until a restartApplication or browser refresh is done.

       

      Implementing PortletLinstener showed that the first time, these methods are called in sequence : init (from Vaadin Application class), handleRenderRequest then handleResourceRequest. handleResourceRequest is called with an UIDL resource ID, which as far as I understand is a UI definition. But now if portlet window is changing state for any reason, only handleRenderRequest is called.

       

      I've tried to force a repaint in handleRenderRequest using for instance (vaadin framework) :

       

      mainWindow.setContent(mainLayout);

      or

      mainWindow.executeJavaScript("wnd.location.reload(true);");

      or

      mainWindow.requestRepaintAll()

      or

      mainWindow.requestRepaint()

       

      but without any succes :-(

       

      Really hope someone has allready faced this problem : I don't know where is my mistake

       

      Any hint, any link, any help would be very appreciated.

       

      Thanks a lot for your help.
