Subject Re: Session Replication
Date Wed, 05 May 2010 20:57:15 GMT
My experience with Tapestry (4 & 5) serializing a DataObject to the
HTML (which it does by default when you have a loop in a form) is that
the deserializing of the DataObject (on the subsequent
request/response) gives you a DataObject that is disassociated from
the DataContext (not good).  Perhaps if the DataContext went along for
the ride all would be well ...

Thanks,

mrg
