MVC with Freemarker

I know this is a little beyond the scope for Freemarker, but...

We're designing a new app, and I'd like to use Freemarker as the 
template engine. Freemarker really only handles the "V" in the MVC 
pattern, though. We're going to do the "M" on our own. What are other 
people using for the "C" part?

In particular, are there any libraries out there that make it easy to 
load / save form data? Here's the sequence:

1. Customer requests a customer record.

2. We fetch it from the db, copy it into a TemplateModel-compatible data 
structure.

3. Render the template, putting the data into form fields like this:

<input type="text" name="foo" value="${foo}"/>

4. User edits data, hits a "save" button. Form gets posted back to the 
server.

5. Form data get magically copied back into the data structure, which we 
can then use to update the db.

(Actually, on #3 above it would be nice to omit the value="" part and 
have the system handle it automatically).

For step #5 it wouldn't be too tough to write code that looped through 
the Request.getParameterMap() and filled up the data model. The trouble, 
though, is that when you render a list or table of values, like database 
records, and you let the user add or edit more than one record at a time 
on the client side, you've got to implement some kind of fancy naming 
convention for the form field names so you can keep them in sequence. 
The Request just brings back an unordered list of name/value pairs, so 
unless you've got a naming scheme, you can't know that the user edited 
record #3 on the page and added records #9 and #10. Same problem occurs 
if you let a user reorder rows in a table.

I'd really rather have a framework do that work for me.

What are other people using?

We've fooled with Ruby on Rails, Grails, and a few others that manage 
the whole MVC stack from database to UI, but none of them really fit the 
bill.
