[Zope] Can't access a method 'in this context'

[Tim Hicks]

I have a XronDTMLMethod with the following body:

----
<dtml-let zoffice="superValues(['ZOffice Converter'])[0]">
<dtml-call
"zoffice.getConverterByName('AsyncZlaveClient').fireNextConversion(_)">
</dtml-let>
----

So, it finds the nearest 'ZOffice Converter' instance (in the acquisition
chain), names it 'zoffice', then attempts to do the call in the middle line.

My ZOffice class has the following method defined:

----
def getConverterByName(self, converterName):
    """ """
    return self._pluginConverters[converterName].__of__(self)
----

self._pluginConverters is a class level dictionary with keys of converter
names and values of converter instances.  The converter instances inherit
from Acquisition.Implicit.

However, when I 'Trigger' the XronDTMLMethod, I get the following error:

----
Traceback (most recent call last):

So, my question; why can't I call this method of my converter object?
