Sorry, maybe I'm not expressing my question accurately.
I understand this is NOT the right approach for implementing this
specific case, but I'm using it as an example to ask for that OGNL
expression.
Finally, I believe I have found it (it works for me):

It's not the syntax that's an issue, it's how you're implementing your data
transfer.
There's no "syntax" for retrieving a persisted object by ID beyond what
OGNL's expression language (EL) provides. You can call arbitrary methods.
The problem with doing that on the view layer on a row basis is t
Yes, that the obvious way. Thank you.
But guess there is some situation where the view needs asking to the
controller for some data passing some parameter. Although the example
is not the best one, suppose PersonAction has Map get
Countries(), which is called in prepare(). Is there any syntax
If you only have an ID then you need to join the Country model; this seems
obvious.
You should do all that on the Java side to avoid the N+1 issue.
