[Solved] aggregate functions not recalcing on filter

[David Ocasio]

Internal  build 823 seems to have a bug.

Used to be if i filtered a column a "count" aggregate function would recalc.
Now it doesn't even if i call ".CalculateAggregates()"

Please see attached snapshots.

The page I am using to demonstrate has not been changed for ages.

Blue Header screens are from an older build most likely the standard 712.
Red Header is using the 823 build.

As you can see it did calc and now it doesn't.

please advise
thanks

As a followup.
For sake of my sanity I made an demo project and tested with 712 and 823 and got the same results.

712 recalcs
823 does not recalc

Please review pasted code.

thanks

Hi David Ocasio,

It is quite possible that you have located a bug. Could you please send us this small dummy project and we will debug it immediately to see what is going on. We need a runnable sample project that exhibits the erroneous behavior -- this will be the fastest way to identify the culprit.

Regards,
Ross

Ross,

Since the forum does not allow project or zip files
i have opened a ticket (461574)
and inclueded the project and snapshots there

I will post any results here for posterity.

thanks

Confirmed as bug,

VVVVVVV
We confirm the issue with the column aggregates. We currently work on resolving it and we will do our best to provide a fix for it in one of the next internal builds.
^^^^^^^^^^

I will post the resolution when it comes for the forums

thanks
dco
