# Capcana: coloana noua intr-un grid existent ajunge la coada (preferinte GridExtras)
`GridExtras` (`COMUN\utile\GridExtras\gridextras.vc2:1051`, `restoregridpreferences` /
`savegridpreferences`) salveaza **per utilizator** latimea si ordinea coloanelor fiecarui grid,
in `%APPDATA%\...\gridprefs.tmp`, sub cheia `SYS(1272, grid)` (ex. `frm_modific2024.grid1`).
Salvarea se face live, la `columnmoved`/`columnresize`, nu la iesirea din formular.
Consecinta: `ColumnOrder` setat in clasa e neutralizat la runtime pentru orice utilizator care a
deschis deja formularul inainte de livrare - `gridextra1.setup()` restaureaza ordinea veche, iar
coloana nou adaugata (care nu exista in preferinte) ajunge ultima.
Solutie: repozitionare la runtime, in `Show()`, **dupa** `gridextra1.setup()`, aplicata o singura
data - cat timp preferintele salvate nu acopera toate coloanele (implementat pe
`frm_modific2024`, `COMUN\clase\omodificari.vc2`, coloana `nnir`).
La testare: pozitia coloanei nu e o asertiune stabila intre masini. Se asertesteaza tare
`ControlSource` si `ReadOnly`; `ColumnOrder` ramane informativ.
