Using the Community version of JasperReports Server since v6, I have created numerous drilldown (Hyperlink ReportExecution _report method) to other JasperReports off charts, text fields, table columns all running fine.
Only the main top level report actually requires the user to input some parameters so the "Input Control" is checked and shown - the other drilled down reports are driven off the main and/or preceding reports.
When the JasperReports Server "Back" button is clicked in a drilled down report, it goes back up to the calling report fine, all the way back to the top level main report where the "Input Control" parameters input report WITHOUT being prompted for parameters...
Since v6.4 (all variants), when the JasperReports Server "Back" button (or even the browser's back button) is clicked AND returning back to the top level report, the "Input Control" parameters is displayed with the default values ie the previously entered values are lost.
If the same reports are imported into a v6.3 JasperReports Server, this drill down/return to the main report WITHOUT triggering the main report parameter Input dialogue works again. See attached example MainContainer report hyperlinking to DrillDownLevel1 report.
Help! I can't seem to figure out why or how to stop this happening!
