Item context menu is not updated upon interaction

[BaerMitUmlaut]

Mods (complete and add to the following information):

• Arma 3: 2.02
• CBA: 3.15.2

Description:
The item context menu is never updated, even when an action is executed. This can cause conflicts between mods, since one mod can add an action that leaves the menu open, but should disable or enable a different action. In my opinion, this is an oversight and can cause unexpected behaviours.

Steps to reproduce:

• Execute the following:

  [
      "acc_pointer_IR", "POINTER", "CONSUME", [], "", {true}, {true}, true
  ] call CBA_fnc_addItemContextMenuOption;

• Use the action

Expected behavior:
The action should disappear.

Additional context:
The easiest and most solid solution would probably be updating the menu through an inventory player event handler.

What do you mean by "is never updated"? Does the old action appear on the next item on the list or?

[BaerMitUmlaut]

The actions remain the same, regardless what happens with the item. If the item gets replaced or removed completely, the context menu stays open with the same options, which may not be valid anymore.

This is a user error. The correct way to make a consumable item is to make the statement return false (or anything else that is not true including nil).

[ 
    "acc_pointer_IR", "POINTER", "CONSUME", [], "", {true}, {nil}, true 
] call CBA_fnc_addItemContextMenuOption;

Additionally, the action is already not executed multiple times, so even if this bug is present, no exploit can come from it:

[
    "30Rnd_65x39_caseless_mag", "CONTAINER", "CONSUME", [], "", {true}, {
    systemChat str ["consumed", diag_frameno];
    true
}, true] call CBA_fnc_addItemContextMenuOption;

The correct way to code a consuming item with a menu that sticks around is:

[
    "30Rnd_65x39_caseless_mag", "CONTAINER", "CONSUME", [], "", {true}, {
    params ["_unit", "_container", "_item"];

    systemChat format ["%1 consumed %2 from %3 - frame: %4",
        name _unit, _item, typeOf _container, diag_frameno
    ];

    _item in magazineCargo _container
}, true] call CBA_fnc_addItemContextMenuOption;
