DataSet.aggregateData returns NaN when aggregating data nodes with just a single value about axiis HOT 4 CLOSED

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.
