[Zope] Accessing an object from a list

[Alexandre Ratti]

Hello,


I ran into this problem once again: what is the best way to access an 
object whose ID is stored in a list?

Here's my setup: I use a form with check boxes to select object IDs. The 
values for the selected boxes are send to the handler method in a list 
(myList). Here is the code in the handler method.

<dtml-with REQUEST>
...
<dtml-in myList>
   <dtml-let foo="_['sequence-item']">
     <dtml-with "_.getitem(foo, 0)">
       <dtml-var myProp1> - <dtml-var myProp2>
     </dtml-with>
   </dtml-let>
</dtml-in>
...
</dtml-with>

I was lucky because this actually works. However, it looks kludgy. Is there 
a better way? For instance, can I use the 'mapping' attribute in the with tag?


Thanks.

Alexandre
