Removing the “Loading..” message while navigating between pages in a report in JasperReports Server 7.9.

Problem:

The “Loading...” message between navigation of pages for a report on JasperReports Server may seem to be disruptive for user experience which was not seen in versions prior to 7.9 JRS.

Cause:

This was an intentional change in the 7.9 JasperReports Server. The report viewer has been refactored to use the same code as the dashboards, so that our product uses a single report viewing API, which works the same way everywhere. The "Loading.." message appears because each time we click the next page, it sends a request to the server and we have to wait for the 2nd page generation. Hence, this is by default how the jasperserver is designed to function in the 7.9 version.

Resolution:

As a workaround for this, you will need to make changes in the <js-webapp>jasperserver-proscriptsruntime_dependenciesbi-reportsrcbireportReport.js file. You will need to Comment out 'controller.view.showOverlay()’ in the file and this will resolve the issue.

Also, as we are making changes in the javascript file you will need to follow the below documentation to optimize the scripts to get the changes reflected on the server if optimization has been enabled on your JasperReports Server.
