How does the application fail? Does it freeze, raise an exception,
crash the system, freeze the system, lock up?

I set up a debug log and have some good and some bad news.

Good news: the allObjects() call now works (I had another call that was just
before it that was actually causing the problem).


Bad News: There's nothing (apparently) in the array. Any attempt to access the
array throws a NullPointerException and when I use the count() method on the
array it comes back with 0 (zero) objects in the array.


I also get null pointer exceptions when I attempt to access the selectedObject,
as well.


The object (displayGroup) is declared and its values appear on the page but, for
some reason I'm not aware of, I can't access those values in memory. Which, for
me at least, is confusing.

Yeah, I'd be confused too.

When are you asking for the values? Is it too early in the request response loop (before the DG's had a chance to fetch the objects)?

Are you sure you are talking to the same DG that's setup in your .woo file?

Try this: add a WOString to your page, bind it to "yourDisplayGroupName.allObjects.count" it should give you the count of all of your objects.
