Aggregation with filter in question [message #921906]

I've tried to use an aggregation to count the data in a grouped table with a filter of the information "date".
I counted the number of data in a month with this filter expression: BirtDateTime.month(row["date"]) == 1

The version of the BIRT I used is 2.3.2 .

My problem is that if there's no data for the month (data that verifies the filter condition expression), the table shows nothing instead of 0.

Is this something configurable and how to configure it?
If else, is this a bug known of the version I used? (I've done some reaserch but I don't find a similar topic.) In this case, is there any possible script solution for my problem?

Thank you in advance.

Add an oncreate script on the aggregation element that has this value:
if( this.getValue() == null ){
this.setDisplayValue(0);
}

The solution works well in my local environnement, when I imported my report on the server. The script doesn't work any more.
Do you have any idea what could be the cause of the problem? It this possibly configuable somehow?

Thanks in advance.

What server are you using? Do you get an error?

It's the application Maximo 7 with the server Webshpere which runs the reports.
I think that it calls a applet java to run the reports, but I'm not sure.
I don't have the error in the log of the server.

You do not get any errors? It just does not set the value? Does it matter if you move it to the onrender script instead of oncreate?

Thanks again, it works on the two sides when i move the script to the "onRender" event.
It's although strange to have a different behavior for the "onCreate" event in the viewer and in the server.
The point is that it works now. Very Happy

My guess would be one is using a runandrender task and the other is using a run task followed by a render task which changes the event order.
