Q: 

How can I access the in-progress SummaryRow in the summaryFunction of a GroupingCollection?

In Flex 3, I'm using a GroupingCollection to create a hierarchical display of data in my app. One of the summarizations I'm doing requires access to another value in the summary row; I'm calculating the average of a column in one place that is necessary for the calculation of a related value in a second summary column. This related value is calculated using a custom summaryFunction.

summaryFunction is passed the iterator over child rows, but nothing else; is it possible to access the SummaryRow to which the summary function will be writing its output?
