Try it like

    c = self.getClients()

The "self" in an External Method can be used like "context"
in a Script (Python).

self.aq_parent is the context's parent in the acquisition chain.
So it involves the calling context as well as the containers,
depending on how the method is called. 

container in a script means the container where the script actually
lives, so it's not affected by context at all.
