Table Aggregation Using RowNum Expression

Maicon Schelter · June 19, 2015

Hi guys,
 
Recently I open this bug here: <a data-ipb='nomediaparse' href='https://bugs.eclipse.org/bugs/show_bug.cgi?id=468529'>https://bugs.eclipse.org/bugs/show_bug.cgi?id=468529</a>.
In Birt Report Design v4.4, in one row of my table I use a aggregation component. In expression I put a rownum property. But in emitter occur an error, when old version (v3.7) does not occur.
 
Someone else with the same problem?
 
Thanks!

While you wait on your bug to be addressed, a workaround could be to select your table, go to the binding tab, choose "Add Aggregation", set up this new aggregation as a runningcount, and finally, go back to your original aggregation and replace your row.__rownum with the new aggregation.
 
Hope this helps.

Hi Williams,
Wondering if this issue has been fixed, but I saw the bug is still open, so I decided to reply on this thread.
I falled into this issue as well. I tried your workaround, however I got below error :

So in my case, my original aggregation let say "Aggregation_ori" have expression rowNum, function "MAX" and filter from another row as well.
Then I followed your post, by adding another aggregation letsay "aggregation_RC" with function "RunningCount", and replace original rowNum with this "aggregation_RC"
 
Attached the screenshot for better understanding
