 /**
 29   
  * ServiceLink used to discard all cached data (templates, specifications, et cetera). This is
 30   
  * primarily used during development. It could be a weakness of a Tapestry application, making it
 31   
  * susceptible to denial of service attacks, which is why it is disabled by default. The link
 32   
  * generated by the ResetService redisplays the current page after discarding all data.
