Bug ID: 159973
Summary: queryPrecedents returns cells as if in same sheet
Product: LibreOffice
Version: 7.6.4.1 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: BASIC
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: patrick.tra...@t-online.de
When I use queryPrecedents to get the precedents of a formula, the
ScCellRangesObj returned behaves as though all precedents were in the same
sheet as the cell itself.
It also seems to me that enumerating the precedent cells only returns the first
one, but I am not 100% sure that I am doing that right; that would probably be
different bug anyway.
(I tried enumerating them to see if that functionality was any better, but
inspecting the object in the debugger suggests that it would not.)
I apologise if this has already been reported; searching for "queryPrecedents"
seemed to cause the site to hang!
I am running this version:
Version: 7.6.4.1 (X86_64) / LibreOffice Community
Build ID: e19e193f88cd6c0525a17fb7a176ed8e6a3e2aa1
CPU threads: 8; OS: Linux 5.3; UI render: default; VCL: kf5 (cairo+xcb)
Locale: en-GB (en_GB.UTF-8); UI: en-GB
Calc: threaded
The following code displays the message:
Formula: =A2+A6+Bug_Prec_Loc_2.A1+A4
Precedents: AbsoluteName =
$Bug_Prec_Loc_1.$A$1:$A$2,$Bug_Prec_Loc_1.$A$4,$Bug_Prec_Loc_1.$A$6
Precedent cell names: $Bug_Prec_Loc_1.$A$1
Enumerated: $Bug_Prec_Loc_1.$A$1
I think it should display something like:
Formula: =A2+A6+Bug_Prec_Loc_2.A1+A4
Precedents: AbsoluteName =
$Bug_Prec_Loc_1.$A$1,$Bug_Prec_Loc_1.$A$4,$Bug_Prec_Loc_1.$A$6,$Bug_Prec_Loc_2.$A$2
Precedent cell names: $Bug_Prec_Loc_1.$A$1 $Bug_Prec_Loc_1.$A$4
$Bug_Prec_Loc_1.$A$6 $Bug_Prec_Loc_2.$A$2
Enumerated: $Bug_Prec_Loc_1.$A$1 $Bug_Prec_Loc_1.$A$4 $Bug_Prec_Loc_1.$A$6
$Bug_Prec_Loc_2.$A$2
Option Explicit ' Require variables to be defined
