Check out https://issues.apache.org/jira/browse/TAPESTRY-2491.
The encoder in use here is the PrimaryKeyEncoder. The encoders
contributed by tap-hibernate are ValueEncoders.
There is currently no bridge between them.
There is also currently no way to map between the two encoder spaces.
There is also no way to "nicely" lookup a PrimaryKeyEncoder, the way
there is with ValueEncoder.
For now, you'll need to provide your own PrimaryKeyEncoder.
It can (probably) be a wrapper around the value encoders.
Cheers,
Robert

Hello again,
I have another issue related to the one about checkboxes that I've
known
would be an issue at whatever point I needed to use dynamically
created
form components. In my case I'm creating a bunch of t:checkboxes, each
representing the (un)selection of a hibernate entity. I'm currently
stuck with two issues:
1) I need an encoder, apparently. I use a loop over the entities
within
a form to create the checkboxes, and T5 throws an exception saying:
Render queue error in BeginRender[info/Buyer:loop]: Error serializing
component action for component ...
Isn't tapestry-hibernate's PK encoder supposed to handle this? In an
effort I set the form to t:volatile="true", but that seems to make it
impossible to access the current object (loop's value parameter)
within
the iteration, which I have. Why isn't the value encoder kicking in?
2) I need labels for the dynamic checkboxes, which means I need to
know
the t:id's of them. How is this possible when looping?
Hasn't someone dealt with this?
Thanks in advance,
Chris
