I need TO add a column sum to column footer of table object for each page.
If I create variable and set sum aggregation function than sum value appear for full report. But I need sum column data for each page, not for full report.
Can anyone help me solve this problem?
This is not a solution for the jr:table component since it uses a subdataset where its not allowed to set resetType="Page", but using a subreport it can be used.
I don't think there is a work around in components (jr:table,jr:list) using a subdataset but would be happy If someone can prove me wrong
Solution using subreport
On your variable set resetType="Page"
es.
<variable name="var" class="java.lang.Double" resetType="Page" calculation="Sum"/>
....
</variable>
For more info on resetType see JRVariable API
On your textField set evaluationTime="Page"
es.
<textField evaluationTime="Page">
....
</textField>
For more info on evaluationTime see JRTextField API
