[Zope] Int to String

[Alexandre Aguiar]

Im working with folders wich the ids are the years (2000, 1999 and so on).

Im trying to list a folder using the following code:

<dtml-with ZopeTime>
  <dtml-let ano="year()">
        <dtml-in expr="ano.objectValues()">
        <dtml-var id>
        </dtml-in>
   </dtml-let>
</dtml-with>

The year() function returns an Int, so when I call 'ano.objectValues()' zope
does not understand it, because it is waiting a string.

How can I turn my Int into a string? Or how can I make this easier?

Thanks for the aid
