Using Enums

Freemarker has been working fine so far writing out pojos. My pojo is
called Calculation and a list of them is passed into the template:

 List<Calculation> calculations = new ArrayList<Calculation>();
        calculations.add(instance1);
        calculations.add(instance2);


In the template I use <#list calculations as c> to be able to do
something like this: c.name.

No issues.

I have attempted to go one step further and make the Calculation an
enum. The reason for this is there is a set amount of possible
Calculation instances (what I mean by this is a set amount of possible
states for Calculation objects).

Now I am doing something like this:

 List<Calculation> calculations = new ArrayList<Calculation>();
        calculations.add(Calculation.NUMBER_ASSIGNMENTS);
        calculations.add(Calculation.NUMBER_ASSIGNMENTS_EST);

When I try and run the template I get the following:

freemarker.core.NonStringException: Error on line 564, column 93 in
claimsTemplate.ftl
Expecting a string, date or number here, Expression c.name is instead

When I do a search on FreeMarker and Enums I find myself reading about
the TemplateHashModel. But I am not sure this is what I want.

I basically want to put a list of enums and have FreeMarker access
their members like the Pojos. Is this possible? I am pretty new to
Enums, am I mis-using them in this case? Does anyone know a better way
to do this?

Thanks!
