[Zope] Can I restore the HTML-form tags from the REQUEST.form

Hi, Is there any method which can restore the HTML-form tags from the REQUEST.form? I mean if REQUETS.form = {'key1': value1, 'key2':[value2-1, value2-2]} I can get: <input name="key1" type=hidden value="value1"> <input name="key2:list" type=hidden value="value2-1"> <input name="key2:list" type=hidden value="value2-2"> It's convenient for me to pass data between several forms , such like the steps in a "wizard". Thanks. Iap, Singuan
