 ... but this should work, except if 'required' or 'hidden' is something more
complicated than a value; in the latter case the condition is always true.

 Maybe You just want to display these values for debugging, e.g.
<span tal:content="python:repeatfield.required" /> and look at what You
get. If e.g. this is actually a method, You may want to try something like
 
  "python:repeatfield.required() and ..." 

instead.
