Ely,
Had similar issue couple of weeks back, can't send code now as it is
on-site inside real-time trading system, but in short if you start with
empty dataProvider populate in real-time and have attributes
like form="curve" and interpolateValues="true" and you get error
similar to above.
Should be easy to simulate going from any emply collection/adding one item
at a time.
Thank you,
Anatole

Hi Tom.
I'm not sure, but that actually doesn't look like it's the same problem.
Can you send me a simple 1-file sample offline?
Thanks.
Ely.

ColumnSets
Bump.
So, is it clear from this error message that this is the same
bug, or
is there a way around it?
Thanks.
