Bug 144153 [regression] drill through to a report with parameter does not work properly
steps to reproduce: - use the attached report design (new_report_2.rptdesign contains a drill through link) (new_report_3.rptdesign contains a parameter without default value) - preview new_report_2.rptdesign in HTML and PDF - click on Carine expected behavior: - drill through to new_report_3.rptdesign - parameter dialog should be displayed actual behavior: - browser internal error
