Hello, I wrote a Testing Vaadin code and I get different output: (The code is the same):

OUTPUT IN LOCAL SERVER ATTACHED1

OUTPUT IN GOOGLE APP ENGINE ATTACHED2.
Mmicoe Google AppEngine

Code is the same !!!
1. Deploy to AppEngine is fine.
2. AccordionIconsExample is not shown in AppEngine.

What is happening?

All the best,
Mauro M.E

Hi,

This is almost impossible to say w/o code, but: Did you configure the things necessary for GAE? That includes enabling session support in GAE and using the GAEApplicationServlet instead of the standard one.

Hmm.. That's strange... Some things to check:
1. GAE and Vaadin app configured as in the book
2. browser has cookies enabled (or maybe other dev settings enabled/disabled?)
3. clear cache, restart browser, etc - the usual suspects...

Note that number 1 must really be done - even if the application might seem to work, it will eventually fail if you do not do this.

Best Regards,
