GateIn 3.1 and Vaadin 6.7.3

[jobijop]

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.

In GateIn, whenever you refresh browser, the portlet content is rendered, initApplication function in Vaadin framework is invoked to create HTML content and update to the portlet.

If Portlet is minimized - normalized or maximized, there is an ajax action, and portlet content is re-rendered as well in ajax response, however Vaadin doesn't want to render the application if it has been initialized, you can see that clearer than in Vaadin 7.0 SNAPSHOT http://dev.vaadin.com/git/?p=vaadin.git;a=blob;f=WebContent/VAADIN/vaadinBootstrap.js;h=1f5f3fa9734a318f181df2bba2aac89278ec1771;hb=HEAD#l71
