Creating a whole bunch of Elements dynamic from code

I double checked by giving the lables text and putting d(row) into the code - it is executed and the items are created. They are just not shown. I asume that I am adding them on a level too high or that something in my window is wrong.

Its because rows are not properly anchored to the window.

Try this code:

<GuiXml>
    <Controls>
        <Control name="EventExplorerRow" virtual="true">
            <Dimensions y="25"/>
            <Controls>
                <Label name="$(parent)Id" font="ZoFontGame" horizontalAlignment="RIGHT">
                    <Dimensions x="60"/>
                    <Anchor point="LEFT" />
                </Label>
                <Label name="$(parent)Name" font="ZoFontGame">
                    <Anchor point="LEFT" relativeTo="$(parent)Id" relativePoint="RIGHT" offsetX="20"/>
                </Label>
            </Controls>
        </Control>
        <TopLevelControl name="EventExplorerWindow" mouseEnabled="true" movable="true" clampedToScreen="true" hidden="true">
            <Dimensions x="760" y="650" />
            <Anchor point="CENTER" />
            <Controls>
                <Label name="$(parent)Title" inherits="ZO_WindowTitle" text="Event Explorer" />
                <Button name="$(parent)Close" inherits="ZO_CloseButton">
                    <Anchor point="TOPRIGHT" offsetY="3" />
                    <OnClicked>
                        EventExplorerWindow:SetHidden(true)
                    </OnClicked>
                </Button>
                <Control name="$(parent)Container" inherits="ZO_ScrollContainer">
                    <Anchor point="TOPLEFT" offsetY="30" />
                    <Anchor point="BOTTOMRIGHT" />
                </Control>
                <Backdrop name="$(parent)BG" inherits="ZO_DefaultBackdrop" />
            </Controls>
        </TopLevelControl>
    </Controls>
</GuiXml>

local LCM = LibStub("LibConstantMapper")
 
local dataList = {}
local lastRow 
 
--get the list of Events
local Events = LCM:getDataByMapping("Events")
 
local function fillWindow()
    for key, value in ipairs(Events) do
        local row = CreateControlFromVirtual("$(parent)Row", EventExplorerWindowContainerScrollChild, "EventExplorerRow", key)
        if key == 1 then
            row:SetAnchor(TOPLEFT, EventExplorerWindowContainerScrollChild, TOPLEFT, 0, 0)
        else
            row:SetAnchor(TOP, lastRow, BOTTOM, 0, 0)
        end
        row:GetNamedChild("Id"):SetText(tostring(value.value))        
        row:GetNamedChild("Name"):SetText(value.key)
        lastRow = row        
    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)

EDIT:
By the way list of events in your library contains global reference to EVENT_MANAGER.
Updated mapping:

{ mapping = "Events", pattern = "^EVENT_", exclude = "^EVENT_MANAGER"},
