Communication problem : "invalid security key"

I have vaadin application with multiple browser tab support. If I launch the application in two separate browser windows directly, it works fine. But when I launch it in embedded iframe in a pop-up window, and do this multiple times, I get this communication problem consistently.

I am using firefox 10 + tomcat 7 + vaadin 6.7.2

Any help is appreciated

You should grab the stack trace out of your sever log and that can show you where to step through the code in a debugger. Since all of the source code is available, that may be faster than waiting for someone else to try to reproduce this. Then you'll have a better idea of what the actual problem is to ask about it.

If you're using maven to build your app, then debugging is even easier -- your IDE should just grab the code as needed. I think you'd want to step through the AbstractApplicationServlet#service method, but that's just an educated guess.

Thanks Bobby, problem was with trailing slash in application uri.

Cool! I love it when a problem turns out to be that easy to fix (though those issues seem harder to diagnose often).
