Not sure what you mean, but it sounds kind of iffy. :-)
Without this recursive pattern, I am not able to perform the parent
action since the action method is not in my DialogBox.java, but on
it's parent, one of my pages say TestPage.java.
If it is on the top level page, you can just do
context().page().valueForKey(actionName);

If a form was submitted, it should "just happen". Things to check:
I am not sure if this means that by invoking an action from within a
form, that is equivalent to submitting the form... even if the action
is being invoked from a subcomponent?
No. You need to submit the form client side. Calling
this.form.submit(); in JavaScript will work, but that is for the
form's action. It sounds like the buttons in your dialog are not
submitting the form.
1. Are the form values in the URL / content of the request?
Maybe this is my problem. Every time I log the
context.request.formValues it is null.
2. Have you overridden takeValues... someplace and forgotten to call
super?
I checked and all takeValuesFromRequest are calling super and not
overridden.
3. Can you add logging and see if takeValues is getting called on the
top level page?
I added takeValuesFromRequest (w/logging) to the top level page, to
its subcomponent (DialogBox.java) and DialogBox.java's subcomponent -
SimpleButton.java. It is not being called anywhere.
All this lead me to think that there is some other "hidden" form. I
am going to look around in the mean time.
I'd look at your buttons and how they render in HTML.

I think those two lines are functionally equivalent.
Agreed. But without it, I am getting
com.webobjects.foundation.NSKeyValueCoding$UnknownKeyException which
does not get caught in my catch statement. I am java-weak :-(
Try just
results = component.parent().valueForKey(actionName);
No need to perform the action twice.
