Good afternoon.
The following is for version 3.13
When, for the purpose of generating a drop-down list that references an
interval of cells in another sheet:
DVConstraint.createFormulaListConstraint("SheetName!$A$1:$A$4")
If the referenced sheet ("SheetName") is, after the above line, moved to
another position within the workbook, the dropdown that is then created
references not the sheet named "SheetName" but whichever sheet is at the
position that "SheetName" sheet was at the time of executing the above line.
So, in short, it is referencing the sheet by position and not by name, as I
think that would be expectable.
Thank you.
