Secure Action Buttons for Spell Casting

[Xrystal]

I've been trying to figure this out all day so far and despite searching and looking at the official forums and trying the examples in wowwiki and searching and reading here I cannot see what is going wrong with this bit of code.

If I comment out the Inherited Frames from the CreateFrame method and comment out the SetAttribute lines the addon I have displays the action buttons as I expect them. However, with this code as it is, nothing is displayed. I know I will later have to implement special functions to handle clicks ( unless the inherited frames does that too ) but for now I just want to get them displayed.

Can anyone see anything to explain why secure action buttons are not even displayed when normal action buttons do ?

Thanks in advance.

local function MagePorts_InitPortalButtons()
	MagePorts_PortalButtons = {};
	for i,v in pairs(MagePorts_PortalDB) do
		if ( string.find(v.faction,MagePorts_Faction) ) then
			local SpellName = select(1,GetSpellInfo(v.spell));
			local Available = ( GetSpellInfo(SpellName) ~= nil );
			local ButtonName = "P_" .. v.spell;
			local TextureName = ButtonName .. "_Texture";			
			local IconFile = select(3,GetSpellInfo(v.spell));
			local Button = CreateFrame("Button", ButtonName, UIParent,"ActionButtonTemplate,SecureActionButtonTemplate");			
			Button:SetWidth(36);
			Button:SetHeight(36);			
			local texture = Button:CreateTexture(TextureName,"BACKGROUND");
			texture:SetAllPoints(Button);
			texture:SetTexture(IconFile);
			Button:SetNormalTexture("Interface\\Buttons\\UI-Quickslot2");
			Button:SetHighlightTexture("Interface\\Buttons\\ButtonHilight-Square", add);
			Button:SetPushedTexture("Interface\\Buttons\\UI-Quickslot-Depress");
			Button:SetAlpha(1.0);
			Button:SetAttribute("type","spell");
			Button:SetAttribute("spell",SpellName);
			table.insert(MagePorts_PortalButtons,Button);
		end
	end
end

For those that have wondered the same thing I have spent the day hammering back and forth with a Blizzard MVP on the official forums and finally tracked down the problem that secure frames cannot be anchored to font strings.

Which of course wasn't part of the code I posted *grimace*.
