AIO Handle executes twice

[budasnorbi]

Whenever i called AIO.Handle("AIOExample", "print") from a client event handler my print function on the server side got called twice.
But the client side event handler only got triggered once.

I am on the latest version of https://github.com/liyunfan1223/azerothcore-wotlk/tree/Playerbot

test.mp4

Here is the lua code:
`
local AIO = AIO or require("AIO")

local handler = AIO.AddHandlers("AIOExample", {});

if AIO.AddAddon() then
function handler.print()
print("Hello from client")
end
else
-- Create the base frame.
FrameTest = CreateFrame("Frame", "FrameTest", UIParent, "UIPanelDialogTemplate")
local frame = FrameTest

-- Some basic method usage..
-- Read the wow addon widget API for what each function does:
-- http://wowwiki.wikia.com/Widget_API
frame:SetSize(200, 200)
frame:RegisterForDrag("LeftButton")
frame:SetPoint("CENTER")
frame:SetToplevel(true)
frame:SetClampedToScreen(true)
-- Enable dragging of frame
frame:SetMovable(true)
frame:EnableMouse(true)
frame:SetScript("OnDragStart", frame.StartMoving)
frame:SetScript("OnHide", frame.StopMovingOrSizing)
frame:SetScript("OnDragStop", frame.StopMovingOrSizing)

-- This enables saving of the position of the frame over reload of the UI or restarting game
AIO.SavePosition(frame)

-- Creating an input:
local input = CreateFrame("EditBox", "InputTest", frame, "InputBoxTemplate")
input:SetSize(100, 30)
input:SetAutoFocus(false)
input:SetPoint("CENTER", frame, "CENTER", 0, 50)
input:SetScript("OnEnterPressed", input.ClearFocus)
input:SetScript("OnEscapePressed", input.ClearFocus)

-- Creating a slider:
local slider = CreateFrame("Slider", "SlideTest", frame, "OptionsSliderTemplate")
slider:SetSize(100, 17)
slider:SetPoint("CENTER", frame, "CENTER", 0, -50)
slider:SetValueStep(0.5)
slider:SetMinMaxValues(0, 100)
slider:SetValue(50)
slider.tooltipText = 'This is the Tooltip hint'
_G[slider:GetName() .."Text"]:SetText(50)
slider:SetScript("OnValueChanged", function(self) _G[slider:GetName() .."Text"]:SetText(self:GetValue()) end)
_G[slider:GetName().."High"]:Hide()
_G[slider:GetName().."Low"]:Hide()
slider:Show()

-- Creating a child, a button:
local button = CreateFrame("Button", "ButtonTest", frame)
button:SetSize(100, 30)
button:SetPoint("CENTER", frame, "CENTER")
button:EnableMouse(true)
-- Small script to clear the focus from input on click
button:SetScript("OnMouseUp", function() input:ClearFocus() end)
-- Usually I use UIPanelButtonTemplate for buttons, but I wanted to show and test some custom color texture here:
local texture = button:CreateTexture("TextureTest")
texture:SetAllPoints(button)
texture:SetTexture(0.5, 1, 1, 0.5)
button:SetNormalTexture(texture)
-- Set the font, could use GameFontNormal template, but I wanted to create my own
local fontstring = button:CreateFontString("FontTest")
fontstring:SetFont("Fonts\\FRIZQT__.TTF", 11, "OUTLINE, MONOCHROME")
fontstring:SetShadowOffset(1, -1)
button:SetFontString(fontstring)
button:SetText("Test")

function OnClickButton(btn)
    AIO.Handle("AIOExample", "print")
end

button:SetScript("OnClick", OnClickButton)
print("client")

end
`

Tested on latest version of Trinity Core and it worked well.

OnAddonMessage is probably incorrectly called twice (core side issue), or you have AIO.lua registered twice server side in different directories.
