Hi, i have the same problem and lucky i resolved :p , first remove from WEB-INF/lib all appengine and datanucleus jars that have old version that App engine SDK library. For example in my App engine eclipse library i had appengine-api-1.0-sdk-1.4.2.jar and in WEB-INF/ lib directory i had and old version like appengine-api-1.0- sdk-1.2.1.jar so delete those files.

Prube this. comment from homepage.java add ListPersonalPanel and the wicket tag from the homepage.html, Then run the example an add at least one person, and then undo the comments. And thats all!
