From e2ebd8a64244d266186e9b2043e5b9d284f4eedb Mon Sep 17 00:00:00 2001 From: Owen Leonard Date: Tue, 23 Nov 2021 18:27:21 +0000 Subject: [PATCH] Bug 29530: Fix handling of NumSavedReports preference in reports table This patch updates the way the NumSavedReports preference value is used on the saved reports page so that the setting is correctly incorporated into the DataTable. The patch also expands the description of the NumSavedReports preference in order to clarify the expected behavior when no value is saved. To test, apply the patch and go to Administration -> System preferences and note the value of NumSavedReports. - Go to Reports -> Use saved. - Confirm that the first page of saved reports shows the number specified in NumSavedReports. - In the "Show" dropdown menu, confirm that the number from NumSavedReports is preselected by default. - Expand the dropdown menu to confirm that the NumSavedReports number is positioned sequentially with the default values. For example, if NumSavedReports = "78," the menu options should be "10, 20, 50, 78, 100, All". - Test with various values of NumSavedReports. A blank value should result in the "All" option being selected. A non-numeric or non-positive value should result in the default set of options being used ("10, 20, 50, 100, All").
