Should Zope be able to locate the object there?

This will return a string. Sure, you do not want that!

This should return a NameError unless you passed in
"folder_of_anotherZClass" as parameter (what you did not
as you can not pass parameters...).

Try:

  return context.folder_of_anotherZclass.objectIds('anotherZclass')
