I took the basic window from AIResearch Grid:

<GuiXml>
    <Controls>
        <TopLevelControl name="EventExplorerWindow" mouseEnabled="true" movable="true" clampedToScreen="true" hidden="true">
            <Dimensions x="760" y="650" />
            <Anchor point="CENTER" />
            <Controls>
 
                <Backdrop name="$(parent)BG" inherits="ZO_DefaultBackdrop" />
 
            </Controls>
        </TopLevelControl>
    </Controls>
</GuiXml>

Added merlights template:

<Control name="EventExplorerRow" virtual="true">
    <Dimensions y="45"/>
    <Controls>
        <Label name="$(parent)Id" font="ZoFontGame" horizontalAlignment="RIGHT">
            <Anchor point="RIGHT" relativePoint="LEFT" offsetX="50"/>
        </Label>
        <Label name="$(parent)Name" font="ZoFontGame">
            <Anchor point="LEFT" relativeTo="$(parent)Id" relativePoint="RIGHT" offsetX="20"/>
        </Label>
    </Controls>
</Control>

And made up some basic code to get the table and fill the window with entries:

local uniqueID = "d893fa70102add4c118054adcc1a1f82"
local LCM = LibStub:GetLibrary("LibConstantMapper")
 
local dataList = {}
 
--get the list of Events
local Events = LCM:getMappedData("Events")
 
local function fillWindow()
    for key, value in ipairs(Events) do
        local row = CreateControlFromVirtual("$(parent)Row", EventExplorerWindow, "EventExplorerRow", key)
    end
end
 
local function windowToggle()
    EventExplorerWindow:SetHidden(not EventExplorerWindow:IsHidden())
end
 
local function OnAddOnLoaded(eventID, AddonName)
    if (AddonName~= "EventExplorer") then return end
    
    fillWindow()
    
    SLASH_COMMANDS["/eventexplo"] = windowToggle
end
 
EVENT_MANAGER:RegisterForEvent("MyAddOn", EVENT_ADD_ON_LOADED, OnAddOnLoaded)

I only added the OnLoadedEvent because I got the errors from below and asumed the code was a bit to "early". But that was not it.


And all I get are those error messages and an empty window:

CreateControlFromVirtual failed.  ControlName[EventExplorerDynamicRow1], ParentName[EventExplorerWindow], VirtualName[EventExplorerRow].
CreateControlFromVirtual failed.  ControlName[EventExplorerDynamicRow2], ParentName[EventExplorerWindow], VirtualName[EventExplorerRow].
CreateControlFromVirtual failed.  ControlName[EventExplorerDynamicRow3], ParentName[EventExplorerWindow], VirtualName[EventExplorerRow].

And there is no explanation what exactly went wrong. Or even what remotely went wrong.
