I did not quite follow Henri's idea.
I would do exacly as you suggest- persist just the id and use it.
*maybe* that will work:
<property name="id" persist="..."/>
<property name="object" initial-value="populateId(id)"/>
public Object populateId(Object id) {
return ....;
}
Cheers,
Ron

Ok, does that mean that the best way is to persist the object id and
then simply re-create the object myself on each request?
That's what I'm doing now, I just found that the same set of methods
(detach(), get/setSomeObject(), @Persist get/setSomeObjectId()) keeps
repeating itself in several of my page classes, so I figured perhaps
Tapestry could give me a hand. :)

The client property persistent manager doesn't use the data squeezer;
it always serializes a bunch of objects to a MIME64 stream. A
DataSqueezer is used for objects encoded as listener parameters or as
hidden form fields.

Create a custom data squeezer for your object and register it.
