Hi,
I have a report running in jaspserserver-pro version using custom data source with the parameter REPORT_DATA_SOURCE assigned to the proper class name CustomdataSource. There is an additional method in this class which determines if the report is empty.
When I execute this report it works without any issues. One of the column of the report has a sort component and when I click on this column header I am getting the below error. Could someone advise what could be the problem.
Thanks,
