Hi Michael:
I think changing the return type from Enum to String is not a very good
solution.
It maybe make your JSP get work,but your Java code will become a little

I think the better way is:

(2)in tag , compare it to an enum constant
Hi Michael:
Or you can use another simple solution:
Convert the value to String(by invoke the [toString] method),
before you can compare it to the String constant.
In your case, it should be:

You don't need an ActionForm to capture the variables sent by client

What you used to defined in ActionForm class, is now should be defined in
Action class.

My way to solve this kind of problem:
(1) Use a DTO class as the data modal for columns of each row.
Every column is represented by one property of the DTO class.
For example:

private String name;
private int id;
// getter
I mean:
Representing associated data by a DTO class and then holding DTO
instances in one List
is better than
Holding data in several separated Lists each represent one column.

The value passed to tag attribute is a simple String.
You have to EVALUATE IT as a expression to get the real value.
You can read the source of Struts2 tag lib to study how they evaluate
the expression.
For example:
in class [org.apache.struts2.components.Property]
(This class is invoked by tag )
"no object found" looks like some javascript is running, but it could
not found an object in the HTML DOM.
so, it looks like not an error of javascript file, but an error of
