In a GroupBy table, how are the elements of the row array sorted?

[Cammagno]

I can't figure out how they are sorted, and so how the lines inside each row are ordered.
I made different assumptions (by SORT, by file.name, by file.path), but in some cases none of them seem the real one).

See for example the attached picture (SORT is by file.name):
Why is "Passo Elfico" before "Longevità Esperta"?

EDIT: it seems that it puts last in the list the last edited one.
So, I'll make a feature request to put them in SORT order

Can you share some YAML and the query to help us repro this? I think this is because the group by is messing with the sort order. Let me do some testing.

[Cammagno]

even without any SORT, the behavior is the same, it's totally ignoring the SORT part, they seem to be listed according to last edit time.

Anyway, this is frontmatter:

Tags: "Cat/Talento/Stirpe"
up: "Talenti da Elfo"
next: "Contegno Risoluto"
Entità: "Talento"
Categoria: "Stirpe"
Stirpe: "[[Elfo]]"
Livello: "1°L"

and this is the query:

dataview
TABLE WITHOUT ID
Livello,
rows.file.link AS "Talento",
rows.PreRequisiti AS PreRequisiti
FROM -#TEMP AND #Cat/Talento/Stirpe
WHERE !NotShow AND Stirpe=[[Elfo]]
GROUP BY Livello
SORT file.name

If I make any change to the title or content of one of those notes, it goes to the last position of the list within the cell.

Group by should be stable - meaning the results in each group are in the same relative order as they were before they group.

[Cammagno]

You can also sort after group by... but as in the others fields, you need to add the prefix rows

This would be the best solution, thanks!

EDIT: but unfortunately it doesn't work for me

[Cammagno]

On the other hand, if I SORT and then GROUP, the names inside each row are correctly sorted, but the rows are not

[Cammagno]

The only way I've found to have both rows and lines inside each row sorted correctly, is to double sort, once before grouping and again after it:

Sorting inside an array in the row can't be done directly by the SORT command.
If I look to your output, to sort "Talento" you need to try

TABLE WITHOUT ID
   Livello,
   link(sort(rows.file.name)) AS Talento
...

[Apply directly sort(rows.file.link) not work well (because a link). To contour this, use rows.file.name and after add the function "link"]

[Cammagno]

If I look to your output, to sort "Talento" you need to try

TABLE WITHOUT ID
   Livello,
   link(sort(rows.file.name)) AS Talento

Thanks, this works!
