SSL issue with Vaadin GridLayout (Vaadin 7.6.2)


We have an application which uses the Vaadin (7.6.2) GridLayout to display some simple data (about 1600 cells). When we configure the server with SSL, the application hangs when loading the grid. We think we have tracked this down to a bug in the atmosphere framework which appears to be related to websocket message size.

We have tried to reduce the data sent to the browser, and also using explicit pushes so that data is sent in chunks, but to no avail. Are there any other workarounds that anyone knows of other than converting to a CSS layout (which we’d rather not do if we can hep it as we are about to go into alpha testing)?
