Yes, the expressions above are not valid. Yo are trying to mix a string 
expression with a python expression.

Find out more about TALES (TAL Expression Syntax).

I don't know what 'plone_url' is, but thanks to Zope acquisition you can 
write this as:

   Path expression: "here/mainpage/getnames"

   or Python expression: "python:here.mainpage.getnames()"

   or String expression: "string:${here/mainpage/getnames}"
