Ok, thanks for this example. But I still have a problem: Because even
the forms on this page are dynamically allocated, they are stored in a
vector, and because they are not copyable, I store a booster::shared_ptr
to them instead.
I loop with
<% foreach form in forms %>
But the problem is, that now the following construct
<% foreach w as cppcms::form::iterator in form %>
does not work, because the template generator expects form to be the
object itself (and therefore generates form.begin() and form.end()
instead of form->begin() and form->end() which would have to be used
here). Is there a way around this apart of editing the generated
template afterwards?

Thanks,
Julian
