Nil Argument Error?

Alright so there is this really weird thing going on that I don't quite understand:

term.setBackgroundColor(colors.blue) --> No error, works normally
term.setBackgroundColor(colors.blue, nil) --> Number expected error
term.setBackgroundColor(colors.blue, 0) --> Still Number expected error

local termxsetBackgroundColor = function(_color, _extra)
return term.setBackgroundColor(_color, _extra)
end
termxsetBackgroundColor(colors.blue) --> Number expected error

Can anyone explain? Thanks!

Java side probably just complains whenever the argument count is wrong or if the argument type is wrong.

I'm just going to put my theory out there that I stated in the PM.

I have a feeling it may be something Java-side (I will confirm later). The method signature may be public void setBackgroundColour(int colour, int someOtherInt) and when you supply 2 or more args they're passed to the method, instead of just the first being passed along with the other int that is added in on the Java-side

EDIT: Oh Lyqyd the ninja. haha.

Yeah that's what BIT said. Do you think that this warrants a thread move to the Bug section? Or would it be out of their control due to their use of LuaJ? I don't know the specifics on that stuff :/.

Edit: Ninja'd by BIT :/

Edit 2: Lol Ninja chaining (How I ironic :P/>)
