Todd,
Lately I've only been an occasional user of Tapestry, but my simple
Blog example works pretty well
(http://objectstyle.org/cayenne/examples/index.html - note that this is
a separate example, not the Artist/Painting one). Look at
Home.activateExternalPage() method - it is called when an ExternalLink
is clicked. It is using DataObjectUtils to get the object for ID, but
the object itself is not refetched. It is in the DataContext and is
simply retrieved from there. I set a breakpoint to verify that in
debugger, and sure enough cached Blog object is COMMITTED.
Not sure how DirectLink parameter (de)serialization works, but using
ObjectId rather than DataObject as a URL parameter intuitively seems
cleaner.
