on(Client)ElementDataChange

Hi there, I'm having trouble with my little code. It works, but for some reason it spams the chat and gives me an error saying that "C stack overflow"

addEventHandler("onClientElementDataChange", root, function ( name, oldValue )  
    if getElementType(source) == "player" then 
        local protected = getElementData(source, "protected") or 0 
        if protected == 0 then 
            outputChatBox("Element data was changed back to old value.", 255, 0, 0) 
            newValue = getElementData(source, name, value) 
            setElementData(source, name, oldValue) 
        end 
    end 
end) 

Any help?

Calling 'setElementData' triggers "onElementDataChange"/"onClientElementDataChange". If these events cause 'setElementData' to be called, you get an infinite recursion. You could make a variable that stops the execution of event handler if element data is being reverted. An example:

local revertingData 
  
addEventHandler("onElementDataChange", root, function(dataname, oldvalue) 
    if revertingData then 
        return 
    end 
  
    revertingData = true 
    setElementData(source, dataname, oldvalue) 
    revertingData = nil 
end) 

'setElementData' call in this handler will cause the same handler to be called recursively, but the checking of 'revertingData' variable will prevent the subsequent recursive calls.

Oh yea, you're right! Thanks!
