Subject [Tapestry Wiki] Trivial Update of "CayenneTapestrySqueezer" by BobHarner

Dear Wiki user,

The "CayenneTapestrySqueezer" page has been changed by BobHarner.
The comment on this change is: outdated note.

  == How To Get Cayenne to Work with Tapestry DataSqueezer ==
  To fully benefit from the information below you should be familiar with the workings of
the DataSqueezer and [[http://www.objectstyle.org/cayenne/|Cayenne]].  The key concept to
remember during this explanation is that there must be ONE unique Datacontext for each users
session in the Tapestry webapp.  Now if you are not using the DataSqueezer, it suffices to
simply put the Datacontext into your VisitObject.  This results in a unique Datacontext for
each users session.  However there is an additional hurdle when using Tapestry's DataSqueezer
to serialize and de-serialize Cayenne Dataobjects.  The difficulty is that the ISqueezeAdaptor
interface does not provide a mechanism for accessing the VisitObject, hence no access to the
Datacontext, hence no way to de-serialize your objects.
