I have included two things below:
[1] The table definition as requested
[2] A snippet from a custom class that I wrote as explained next.
(Quick disclaimer: I am using JAR 1.1.1 though I did try to drop test
the latest version of the JAR. The rest of this email refers to the
source code which I got off one of the web source repositories, Koders
Search, and I have not done complete due diligence in reconciling
versions of code to JAR.)
So basically I feel that I have verified the behavior at least. As my
original email states, it seems you can only use properties that belong
to the underlying object. I guess that is fine for now as long as I
understand that. It does not seem as useful but at least I know what to
expect.
So, for what it is worth, I have at least solved my problem temporarily
by writing a custom Decorator modeled after the total decorator in the
JAR. I ended up overriding the evaluate method from the base Decorator
class which I included in [2] below. It is pretty simple and it seems
to work though I have not done a lot of testing against it. I will
update this thread if I find out more.
I am still curious as to the take that others have on this "feature".
My observations are not really a complaint, just trying to flush out my
own understanding and contribute to the process of open-source. If I
get to spend much more time on this I may even post a proposed patch or
something. J
Thanks all.

[Note: I know that these have a body and a property. A mere artifact
of the various things I tried along the way. From my testing,
apparently the property value trumps the tag body so it is merely
"misleading" and does not cause a bug.]

[Note: CheckedExceptionWrapper is a custom class that we use.]
public Object evaluate(String name) {
Object o = null; // super.evaluate(name);
if (this.hasGetterFor(name)) {
try {
o = LookupUtil.getBeanProperty(this, name);
} catch (ObjectLookupException e) {
throw new CheckedExceptionWrapper(name, e);
}
} else {
// else check underlining object
o = super.evaluate(name);
}
return o;
}
