Conditional aggregate [message #258052]

Hi,
I have problem with a report which worked well in older BIRT. I had a data
field which had value depending on a parameter. If parameter had value
"true", data field had a function total(count()) and if it was "false",
data field had total(max()). Is it possible to make such conditional
aggregate in birt 2.2?

thanks,

Yes its possible.

In BIRT 2.2 we have tried to make the aggregation UI more easy to use.

Steps to create conditional aggregate in birt 2.2 would be
- Go the binding and define the required aggregations by clicking on 'Add
Aggregation' button.
Note each binding corrsponds to one function
- Next add a data item from palette and specify the condition expression, in
your case it would be if parameter has value "true" use the value
'aggregation1'
else if valeu = "false" use the value 'aggregation2'
