Need help identifying problem with lua error

[Toez]

I 'created' my own addon at the beginning of the year by taking snippets from here and there, with basically no knowledge of lua. I still have really no knowledge of lua and I'd like some help if solving the error my addon is giving since 4.0.

This is the error:

Message: [string "FishFeastAlertFrame:OnLoad"]:2: attempt to index global 'this' (a nil value)
Time: 12/06/10 20:53:51
Count: 1
Stack: [string "*:OnLoad"]:2: in function <[string "*:OnLoad"]:1>

Locals: self = FishFeastAlertFrame {
 0 = <userdata>
}
(*temporary) = nil
(*temporary) = nil
(*temporary) = <function> defined @Interface\AddOns\FishFeastAlert\FishFeastAlert.lua:95
(*temporary) = "attempt to index global 'this' (a nil value)"

You can grab the code here: http://wow.curse.com/downloads/wow-a...eastalert.aspx

I can see roughly whats wrong but just can't see any way to fix it. Since it's a lot of code snippets I'm not positive on whats going on in places and would like some help please.

Old:

FishFeastAlertFrame:OnLoad();

function FishFeastAlertFrame:OnLoad()
('this' can be used as a reference without specifying it)
...
end

New:

FishFeastAlertFrame.OnLoad(self);

function FishFeastAlertFrame.OnLoad(self)
('this' is no longer available, the first argument is the reference to the object and must be passed as a parameter)
...
end

I forgot to point out '.' vs ':' when declaring/calling functions in a table. See: http://en.wikipedia.org/wiki/Lua_%28...ng_language%29 > Object-oriented programming section

Old:

FishFeastAlertFrame:OnLoad();

function FishFeastAlertFrame:OnLoad()
('this' can be used as a reference without specifying it)
...
end

New:

FishFeastAlertFrame.OnLoad(self);

function FishFeastAlertFrame.OnLoad(self)
('this' is no longer available, the first argument is the reference to the object and must be passed as a parameter)
...
end

Would be easy if

FishFeastAlertFrame:OnLoad()

was there but all of the functions are like

On Load = function () --Minus the space, couldn't post it without the space.

I'll try to fix all of the functions if I get time I guess.
