[Zope] Instance conversion

[Kent Polk]

I am having trouble attempting to access a Confera Topic instance
given it's string name.

I can:
<!--#in "objectValues('Confera Topic')" skip_unauthorized=1 sort=bobobase_modification_time -->
  <!--#if sequence-var-has_items-->
  .
  .
  .
  <!--#/if-->
<!--#/in objectValues-->

or:
<!--#if "testConfera.has_items()"-->
  .
  .
  .
<!--#/if-->

noting that testConfera is a <Topic Instance at xxx>

However, I can't figure out how to retrieve the Topic Instance
given the string name 'testConfera'. I can get several different
types of instances (such as <ResultSet instance at xx>, but not
a Topic Instance.

How to??

Thanks
Kent
