Strange... because I succeeded in reading Enum values from an inner
enum class, like:
public interface MyInterface {
enum MyEnum {
MY_ENUM_VALUE;
}
}
Using
<s:property value="@[EMAIL PROTECTED]"
/>
prints:
MY_ENUM_VALUE
(value returned by the .toString() from the Enum class)
Note: it might be dumb to do this, BUT if you use a specific Struts2
(or XWork?) converter to "translate" your enum value into something
different (e.g. introducing a label or something similar that would
returns "My Enum Value" in our example) then it's useful when not only
dealing with the Enum name (i.e. here MY_ENUM_VALUE).
I also succeeded using
<s:property value="@[EMAIL PROTECTED]" />
that prints:
2.718281828459045
But strangely, some:
<s:property value="@[EMAIL PROTECTED]"
/>
does not work... why?!
... all this with Struts 2.0.11.1

And what if, as from my above explained example, you have an
*interface*, not a class...?
