Bug ID: 99313
Summary: Importing Excel file with installed validity check
based on a formula produces faulty result
Product: LibreOffice
Version: unspecified
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: libreoffice-bugs@lists.freedesktop.org

Build Identifier: LibreOffice 5.1.1.3
I have produced an Excel spreadsheet with a validity check for cells. It
concerns column A.
Cell A1 is the column header.
Cell A2 has validity check by formula: =COUNTIF(A$1:A1;A2)=0. According to
Excel, only values inserted in A2 which amke this formula produce TRUE are
permitted.
Cells A2:A10 are copied down from A1, so that each cell contains a check with a
formula counting the present value among all cells above itself.
Effectively, in Excel cells A2:A10 have a validity check that requires that the
value in a cell is not a duplicate of a value above it. Entering a duplicate
produces a warning message and is rejected, as expected.
LibreOffice does not permit validity check by formula. However, if I download
the file into LibreOffice, the formula from the Excel file somehow gets into
the validity check and causes it to operate in a way difficult to explain.
First of all, "Validity" reports "Allow all values", but there is a (grayed
out) restriction to a valid range, with the formula from Excel shown as the
minimum value, 0 being the maximum.
Next, entry of values into the affected cells is restrcted in a very
unpredictable way.
- one can enter 0 values one by one, starting from top.
- one can enter 1 values one by one, starting from top.
- if one enters a few 0 values, and then a single 1, this input is rejected.
- if one enters a few 1 values, and then a single 0, this input is permitted.
- Entering 2 and string "a" is always rejected, not matter where and if there
are other value sin the cells A2:A10 or not.
Reproducible: Always
Steps to Reproduce:
1. Import the described Excel file.
2. Observe the "Validity" tool.
3. Attempt to insert values.
Actual Results:
As described above, some values are permitted, some are rejected, is a
more-or-less unpredictable way.
Expected Results:
1. Optimal choice: implement validity check by a formula to work correctly.
2. Suboptimal, but reasonable choice: display a warning upon opening file that
some features will be missing, ignore the unsupported validity chcek
completely.
