i get this error message in log and in AlertManager (ClientDataEncoderImpl.java:61) - The symbol 'tapestry.hmac-passphrase' has not been configured. This is used to configure hash-based message authentication of Tapestry data stored in forms, or in the URL. You application is less secure, and more vulnerable to denial-of-service attacks, when this symbol is not configured.
I wish to implement tapestry.hmac-passphrase Hope someone can tell me exactly what to do -- Pozdrav Nikola Vulovic
