DataSet.aggregateData returns NaN when aggregating data nodes with just a single value

What steps will reproduce the problem?
1.Replace the 2008_Olympics.xml with the modified one attached
2.Run the HClusterStackExample
3.Put a debug point at dc.invalidateDisplayList();
4.Look at the aggregates output in the debugger (see screenshot attached)
to see that the medal_count_avg = NaN for South Korea (which was modified
to just have a single gold metal node)
What is the expected output? What do you see instead?
The expected would be the aggeration of the single node, but it returns NaN
What version of the product are you using? On what operating system?
I downloaded the May build version as well as R309 on Windows XP
Please provide any additional information below.
I have attached a screenshot of the debugger as well as the raw xml file
used to simulate the condition.

thanks for submitting this bug report. We are making significant changes to
DataSet, with more strongly typed
classes to support grouping and aggregation. We will be sure to test for
single node collections in
aggregation.

These 'country' nodes should to be wrapped in a root 'countries' node for well
formed XML (in the
2008_Olympics example).
Aggregation is not functional if the XML has a root level node.
This becomes major in dealing with systems using XML typed objects.

I fixed this issue in response to a question on the google group, but I'm only
noticing it here now. Marking it as closed. The fix can be found in the
development
branch.

Hi there, woudl it possible to just post how you fix.
The version you have online is actually quite different from the one I'm using
and it
actually renders my application useless.
Thanks in advance for your time.
