Euclides informed me that when attempting to download the Pentaho report templates from the Mifos UI, he's unable to and faced with a "File Not Found" error.
Not sure if this is related to https://mifosforge.jira.com/browse/MIFOS-5746 which was resolved in Mifos 2.5. In that issue, a stack trace error was generated when trying to download the reports.
This occurred for Euclides on his test server, a production instance of Mifos, and the our demo server (all running Mifos 2.6). I have repro'd this on the demo server.
Here are the steps to repro.
1) Go to Admin
2) Click "View Reports Templates" under Manage Reports
3) Scroll down to any report like MFI Progress or Balance Outstanding and click Download
4) EXPECTED: .prpt file starts to download // ACTUAL: Error of "File Not Found" shows up.
