Functions overriden twice

Hi I am trying to correclty save old references and call them in overridden functions however I get some sort of recursion:

Code:

---

function onInit()
        -- save the old ref
        oldRef = SomeModule.SomeFunction;

        -- replace the function reference with new code
        SomeModule.SomeFunction= new_function;
end

function new_function()
        Debug.chat("1")
        oldRef()
end

---

whenever SomeModule.SomeFunction gets called I get "1" twice in the chat (and the function is executed twice)

however if I "hard" override the function e.g.

Code:

---

function onInit()
        -- replace the function reference with new code
        SomeModule.SomeFunction= new_function;
end

function new_function()
        Debug.chat("1")
        -- <just copy paste the old code here>
end

---

I only get "1" once in the chat and the function in only executed once.

What could this be?

Sorry to have bothered, I have figured it out. My script was sourced in two places, in extension.xml, and in another .xml file, that is onInit was called twice leading to this recursive behavior.
