I don't think there is an easy way to do this currently, although something like [% element.each.join(',') | html %] might work maybe. You should probably urlencode it too, so things like line returns are escaped. You're probably better off just creating your own serialize virtual method that uses base64, though. Also, the each behavior is going to be changing in TT3, so I would be aware of that.

You could also just use a foreach and make a bunch of hidden inputs. Or just store the hash on the server and assign the form a unique id that would associate it with the hash.
