UI IDD Collision Repair

UI IDD Collision Repair

Status: confirmed UI/resource risk, patch-ready. This page owns the exact source evidence and safe repair plan for duplicated idd values in dialogs and title resources.

All source paths are relative to Missions/[55-2hc]warfarev2_073v48co.chernarus/.

What To Read

Current Collisions

description.ext includes the relevant UI resources:

• description.ext:54 includes Rsc\Ressources.hpp.
• description.ext:56 includes Rsc\Dialogs.hpp.
• description.ext:58 includes Rsc\Titles.hpp.

Two dialog classes share idd = 23000:

Resource	Evidence	Runtime owner
RscMenu_EASA	Rsc/Dialogs.hpp:3209-3211	Client/GUI/GUI_Menu_EASA.sqf
RscMenu_Economy	Rsc/Dialogs.hpp:3287-3289	Client/GUI/GUI_Menu_Economy.sqf

Two title resources share idd = 10200:

Resource	Evidence	Runtime owner
RscOverlay	Rsc/Titles.hpp:44-46	Started from Client/Init/Init_Client.sqf:149 on cutRsc channel 1365.
OptionsAvailable	Rsc/Titles.hpp:164-165	Started from Client/FSM/updateavailableactions.fsm:62 and Client/Client_UpdateRHUD.sqf:7.

There is no standalone Client/RHUD subtree in the current source. RHUD is folded into OptionsAvailable plus Client/Client_UpdateRHUD.sqf, so title-ID repair must preserve that display-owner relationship.

Why It Is A Risk

In Arma 2 OA UI terms, duplicated idd makes findDisplay 23000 or findDisplay 10200 ambiguous when more than one matching display can exist or when future code assumes uniqueness.

The dialog collision is more actionable because EASA and Economy both sit near the same control ID range:

• GUI_Menu_EASA.sqf:7 uses listbox control 23003.
• GUI_Menu_Economy.sqf:3 receives a display handle and uses DisplayCtrl 23002.

Current normal flow reduces the chance of an immediate player-visible bug:

• GUI_Menu.sqf:171 closes the previous dialog before opening Economy.
• GUI_Menu_Service.sqf:243 closes the previous dialog before opening EASA.

The title collision is less likely to break creation because cutRsc addresses resources by class/layer, but it can still confuse ID-based debug, findDisplay, or future display-control lookup.

Patch Shape

Keep the first patch small:

1. Assign a new unique idd to one of RscMenu_EASA or RscMenu_Economy.
2. Audit all findDisplay 23000 and hard-coded display assumptions before changing scripts.
3. Keep existing idc values unless a specific control collision is proven after the dialog ID change.
4. Assign a distinct idd to either RscOverlay or OptionsAvailable.
5. Prefer stored display handles such as currentCutDisplay / uiNamespace over ID lookup for title resources.

Do not combine this with EASA balance generation or Economy authority changes. This is resource hygiene and future-proofing.

Generated And Modded Copies

The same collisions are expected in generated Vanilla Takistan and full modded mission copies. Patch source Chernarus first, propagate generated Vanilla with Tools/LoadoutManager, and treat modded copies as a separate maintenance decision.

Validation

Source-only:

• RscMenu_EASA and RscMenu_Economy have distinct idd values.
• RscOverlay and OptionsAvailable have distinct idd values.
• Any findDisplay 23000 / findDisplay 10200 references are updated or proven safe.

Arma smoke:

• EASA opens from service menu and applies/returns as before.
• Economy opens from main menu and income/sell/supply-truck controls still render.
• RHUD/FPS HUD still appears and updates.
• Action availability icons still appear.
• No title resource flicker/regression during map/menu transitions.
