This is not directly supported, but there is a workaround. The property
names, or the subparts of them anyway, can refer to three things:
* getX() methods
* If current result is a java.util.Map, then call get(X) instead
* If current result is a java.util.ResourceBundle, then call
getObject(X) instead

So, it would be possible to do what you want right now by hiding it
behind a Map. 

public Map getProperties()
{
  return new AbstractMap()
  {
    public Set entrySet()
    {
      ... get properties into a Set and return it
    }
  }
}

Then you can refer to it by doing "properties:foo", which will be
equivalent to getProperties().get("foo").

If you do this, please send me the complete code (if that's ok I mean)
so I can add this as an example. As you're probably beginning to see the
magic of WebWork is not in it's API, but in the design and
implementation patterns that one can use. This is one such important
pattern.
