Thanks!

local button = _G[barName .. 'Button' .. j]
local slot = button:GetPagedID() or button:CalculateAction() or button:GetAttribute('action')

works great.
although, could you explain why

function AMine:getListFromDB(DB)
  local items = {} 
	if DB == nil then return "dbEmpty" end
	for index, value in pairs(DB)do
		tinsert(items, index)
	end
	return items	
 end

 button = _G[barName .. 'Button' .. j]

print(self.getListFromDB(button))

yields dbEmpty instead of a slot number?
