[Zope] Converting REQUEST style lists into real lists

When you put into your form: <input type="checkbox" name="varia" value="1"> <input type="checkbox" name="varia" value="2"> <input type="checkbox" name="varia" value="3"> <input type="checkbox" name="varia" value="4"> <input type="checkbox" name="varia" value="5"> <input type="checkbox" name="varia" value="6"> and then select first three of them and submit that form, you'll get in form "action" document: <dtml-var varia> displayed as: ['1','2','3'] Is there an easy way to convert 'varia' into a list? Those inputs are dynamicaly generated from database, and I want to analyse which were choosen in <dtml-in "varia"> block. Or, maybe there is another trick to colect&analyse them in a simple loop? -- Tomek Giela IMAGINATION DESIGN S.C.
