fix nil error in key check

[Uveso]

Resolved nil error in key check; added missing comparison for action.

example table:

ret["select_inview_idle_mex"] = {
    action = "UI_SelectByCategory +inview +idle MASSEXTRACTION",
    category = "user",
    order = 30
}

Can you share your preference file that triggers this logic? And shouldn't it also be applied to the next block:

• fa/lua/keymap/keymapper.lua

  Lines 217 to 223 in d1d28f7

  	for k,v in debugKeyActions do
  	if ret[k] and ret[k] != v.action then
  	WARN(string.format("Overwriting user key action: %s -> %s", k, ret[k].action))
  	end
  	ret[k] = v
  	end

yes you are right, the second block also need a fix.

btw these are the warnings:

WARNING: Overwriting user key action: select_all_idle_eng_onscreen -> UI_SelectByCategory +inview +idle ENGINEER
WARNING: Overwriting user key action: select_inview_idle_mex -> UI_SelectByCategory +inview +idle MASSEXTRACTION

WARNING: Overwriting user key action: toggle_mdf_panel -> UI_Lua import("/lua/ui/game/multifunction.lua").ToggleMFDPanel()

and these are the keys:

UserKeyActions = {
    select_all_idle_eng_onscreen = {
        order = 18,
        action = 'UI_SelectByCategory +inview +idle ENGINEER',
        category = 'user'
    },
    select_inview_idle_mex = {
        order = 30,
        action = 'UI_SelectByCategory +inview +idle MASSEXTRACTION',
        category = 'user'
    },
    select_all_mex = {
        order = 31,
        action = 'UI_SelectByCategory MASSEXTRACTION',
        category = 'user'
    },
    toggle_tab_display = {
        order = 28,
        action = 'UI_Lua import("/lua/ui/game/tabs.lua").ToggleTabDisplay()',
        category = 'user'
    },
    show_enemy_life = {
        order = 2,
        action = 'UI_ForceLifbarsOnEnemy',
        category = 'user'
    },
    teleport = {
        order = 5,
        action = 'StartCommandMode order RULEUCC_Teleport',
        category = 'user'
    },
    toggle_mdf_panel = {
        order = 27,
        action = 'UI_Lua import("/lua/ui/game/multifunction.lua").ToggleMFDPanel()',
        category = 'user'
    },
},
