New bug after upgrading from 4 to 5.
When there is a hyperlink to another report that that has an Input Control, the input control opens but is blank and you cannot get it to display the Input Control properly .
All hyperlinks are created as follows:
Hyperlink Type - ReportExecution
Link Parameter Name - _report
Parameter Class Name - java.lang.String
Value Expression - "repo:/fiolder1/folder2/report_name"
Hyperlinks work correctly where there is no Input Control.
