This is not possible without javascript because one request can only trigger one response.
I believe the most elegant and generic solution can be achieved through the concept of notifications (stackoverflow does this when it displays messages in the top ... and perhaps your app has something similar). So, anyway, imagine flash-persisted messages that your Layout component always outputs (if they exist) only that instead of being displayed directly, they trigger js functions (and in fact those "messages" would really be json). Those functions would then do the correct action in each case by: - either displaying some text in a fancy way - or opening a popup with the given url - or ...
