Hello all,

I have a list of ids which correspond to instances in a folder.  I want to 
iterate through the list and display their properties.
I get an attribute error when rendering the page.

<dtml-in pendlist>
<dtml-call "REQUEST.set('theContainer', _.getattr(transactionInstances, 
_['sequence-item']))">

<dtml-with theContainer>
&dtml-targetcorp;
</dtml-with>
</dtml-in pendlist>

Where:
transactionInstances is the folder containing the instances
pendlist is the list of ids
targetcorp is an attribute of the instance


Can you give me a hint?
