Re: crash report 

Hi,

This is not related to tapestry but your database configuration. Though the nice thing is that the solution is to be found in your stacktrace. Bless Connectior/J for nice exception handling :)

"The last packet successfully received from th e server was 52,974,616 milliseconds ago.  The last packet sent successfully to the server was 52,974,616 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing con nection validity before use in your application, increasing the server configure d values for client timeouts, or using the Connector/J connection property 'auto Reconnect=true' to avoid this problem."

The solution here being to add autoReconnect=true to your db url. Like so:  jdbc:mysql://localhost/jyour_db?autoReconnect=true

Cheers,
Joost
