Subject [Bug 60384] New: ShiftRows unexpected deletion of mergedRegions (due to 59740)
Date Wed, 16 Nov 2016 16:46:32 GMT

            Bug ID: 60384
           Summary: ShiftRows unexpected deletion of mergedRegions (due to
           Product: POI
           Version: 3.15-FINAL
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: regression
          Priority: P2
         Component: SS Common

Template for use case

Due to https://bz.apache.org/bugzilla/show_bug.cgi?id=59740 merged regions are
disappearing even when no overlap was created.

Typical use case:
You have a template like attached with a merged region in row 9.
Row 3 is "template-row":
1. It either gets removed (no prameter)
2. Or it gets filled with just 1 parameter
3. Or it gets duplicated and filled for each parameter

Since I have to add or remove rows with sheet.shiftRows(3,
sheet.getLastRowNum(), n), the merged region in row 9 simply gets deleted.

Merged regions that do not create an overlap with another merged region should
not be deleted just like that. I expect the merged region to shift just like it
did in POI < 3.15
