Hey,

Your examples from your learning vaadin 7 book throws an exception when following the book and using the source from github. Looks like maybe something has changed with the twitter libraries after you published.

Hello,

Thanks for your interest in Learning Vaadin 7. I'd suggest you read section Prerequisites on p. 206 as it will definitely solve your problem if you follow the steps described.

Thanks for the quick response. I'm almost to page 206; so I probably jumped ahead too fast downloading the full project before getting there. I'm enjoying your book! Great job on the book!

Thanks,

David
