can we assume fieldErrors is some sort of List<E> ?

No, fieldErrors is a map, the entries of which are a list--as the JSP
snippet implied, and as in the docs.
<s:if test="fieldErrors.get('email').size() > 0"><s:property
value="fieldErrors.get('email').get(0)" /></s:if>
(would be easier to follow example if we could see referenced variables)
What referenced variables?
