If you want to pass along a hidden list proerty, you'll have three
options:

1. Pass it along as a list of hidden fields with the :list modifier,
Zope will reassemble the list:

  <dtml-in roles>
    <input type=hidden name="roles:list" value="&dtml-sequence-item;">
  </dtml-in>

2. Turn the list into a space-seperated token property. This only works if
there are never any spaces in your list items:

  <dtml-let tokens="_.string.join(roles)">
    <input type=hidden name="roles:tokens" value="&dtml-tokens;">
  </dtml-let>

3. Turn the list into a newline-seperated lines property. This only
works if there are never any newlines in your list items:

  <dtml-let lines="_.string.join(roles, '\n')">
    <input type=hidden name="roles:lines" value="&dtml-lines;">
  </dtml-let>


Warning: this is from the top of my head, YMMV.
