I was afraid of that. Stacking charts in Flex 1.5 have stricter
requirements on the data...namely, all of the items must be present in
the first series, the values must be numeric, and you can't use the same
field name in different series. Flex 2 only requires the values to be
numeric, so your example should work fine in Flex 2. But that probably
doesn't help too much ;)
I can think of two workarounds, neither of which is ideal, but might do
the trick.
1) preprocess your data, and replace missing values with 0.
2) preprocess your data, and do the summing yourself. Instead of
stacking the series, make them each floating columns, with the min value
set to the sum of the previous series, and the max value set to the sum
of the previous series plus its value.
Ely.

Yes, sorry its a stacked series. The first item in the series is always
undefined.
