Because options-enumeration expects the fully qualified name of the
enum,
as a String, and NOT an actual instance of an Enum. Also, useActionBean
is for action beans, not Enums. Either way, you need to pass the name of
the enum. If you need to alias the name, you could use:
<c:set var="EnumHelper" value="buzzlabs.view.EnumHelpers.SiteType"/>
...
<s:options-enumeration enum="${EnumHelper}"/>

Because options-collection, unlike options-enum, expects an instance
of a collection, not the fully qualified name. So, in this example,
the getGeoLocation() method is called on the instance of the
FormViewHelper class, and the collection returned is used.
Hope that clears things up!
