Base with Form showing invalide line count in listbox in table control

I put 2 listbox based on same sql query
One in the form > follows line count (and alignment)
One in a Table control (column "article") > don't follows line count (and alignment)

Comment 4 Buovjaga 2023-10-10 10:58:54 UTC
Can you explain what is the expected result of "line count"? You say

7.click in the column with the listbox
line count 3 is not followed

What does this mean? That the dropdown should only show 3 items?
Comment 5 TISSENDIER Pierre 2023-10-10 11:21:16 UTC
Yes !?
The dropdown should show 3 items  and a vertical scrollbar to show and select other item.

Thank you Pierre.

I reproduce the issue in a recent trunk build:

Version: 24.2.0.0.alpha0+ (X86_64) / LibreOffice Community
Build ID: 9a02f4ed071f15908624fb1cafcf6dbb72b00a1b
CPU threads: 8; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: en-AU (en_AU.UTF-8); UI: en-US
Calc: threaded

Steps:
1. Open attachment 189829 [details]
2. Forms > right-click on Formulaire1 > Edit
3. Right-click on column "Article" in the Table control > Control > General > Line count: value is set to 5 already.
4. Close dialog, turn Design Mode off
5. Expand a dropdown in the Article column

Result: 11 rows shown instead of 5.

This is a regression in 7.0. Both gtk3 and gen VCL plugins are affected.

Bibisected with linux-64-7.0 repository to first bad commit c36e473dd4356f5bf5e8bcdf4b43d32c6f02741b which points to core commit:

Comment 8 Julien Nabet 2024-05-07 15:39:53 UTC
On pc Debian x86-64 with master sources updated today, it always displays 3 articles, whatever the value I put in General > Line count

The property seems to be FM_PROP_LINECOUNT and when git grepping this I got:
svx/source/fmcomp/gridcell.cxx:2464:    doPropertyListening( FM_PROP_LINECOUNT );
svx/source/fmcomp/gridcell.cxx:2498:    // we no longer pay attention to FM_PROP_LINECOUNT
svx/source/fmcomp/gridcell.cxx:2577:    doPropertyListening( FM_PROP_LINECOUNT );
svx/source/fmcomp/gridcell.cxx:2634:    // ignore FM_PROP_LINECOUNT
svx/source/form/formcontrolfactory.cxx:397:                    _rxControlModel->setPropertyValue( FM_PROP_LINECOUNT, Any( sal_Int16( 20 ) ) );
svx/source/inc/fmprop.hxx:91:inline constexpr OUString FM_PROP_LINECOUNT = u"LineCount"_ustr;

I'm not sure why we have a feature like this, it seems an odd thing to support.
