CayenneDataObjects persisting
About a year ago, in Tapestry 2.4, there was discussion about how to
deal with CayenneDataObjects that don't like to be serialized.
The solution involved subclassing DefaultValuePersister and registering
CayenneDataObjects as immutable.
Unfortunately, I can't find DefaultValuePersister in Tapestry 3.0.
Anybody know how to solve the problem currently?
Sorry for posting to both lists, but I figured someone might be on one
but not the other and would have the answer handy.

Could you post a small example of a case where you get a hollow
CayenneDataObject? I've been trying cayenne for the last week and I'm
not seeing this problem. I do pass CDO's from one page to another as
parameters to setter methods. Thanks.

Yep. That's the post I found. And DefaultValuePersister doesn't exist
in Tapestry 3.0, and I still get hollow CayenneDataObjects when I pass
them
as parameters to methods.
My workaround currently is to refetch the object, but it sure would be
nice if I didn't need to do that.
