[Zope-dev] Attribute Error in _call_ with childless_decoration

[Jason Spisak]

Zopeinators:

It worked fine, then all of a sudden, I got a traceback on a document
that uses this code:

<!--#tree branches_expr="objectValues(['Submission'])"-->
<a href="<!--#var tree-item-url-->">
<img src="<!--#var icon-->" border="0"> <!--#with Candidates--><!--#var
"_.getattr(_.getitem(candidate),'first_name')"--> <!--# var
"_.getattr(_.getitem(candidate),'last_name')"--><!--#/with-->
</a>
<!--#/tree-->

It worked Friday, I didn't do any work over the weekend, and now it
gives me this traceback:

<!--
 Error type:  
 Error value: __call__
 -->

Traceback (innermost last):

Any ideas what a childless_decoration is?  The 'Submission' object is a
class that has a property named 'candidate' which containes the id of an
object in the 'Candidates' folder.  I'm not sure what's going on.  Any
insight is greatly appreciated.

Thanks in advance,
