Important: addChildAt function is changed at 2012.08.2

Hi,

As you know, @techdojo reported a bug about addChildAt function at this thread: http://giderosmobile.com/forum/discussion/1553/documentation-bug-or-library-error#Item_1

With version 2012.08.2, index parameter of addChildAt starts from 1. If you're using addChildAt function in your code, you have two options:
1. In your code, increase the index field of addChildAt functions by 1. (e.g. addChildAt(..., 0) should be addChildAt(..., 1)) This is the preferred way.
2. Put this function to init.lua

if application.getApiVersion ~= nil and application:getApiVersion() >= "2012.08.2" then local originalAddChildAt = Sprite.addChildAt function Sprite:addChildAt(child, index) originalAddChildAt(self, child, index + 1) end end

Thank you.

Thanks for the heads up - I'll make sure my code is updated.

EDIT : Updated the code and tested it in 2012.8.2 - I can confirm the fix works and Sprite:addChildAt() works as intended.

will addChildAt(..., 0) crash?
Maybe it would be better I try it myself after get up

I would suggest just "biting the bullet" and changing the code - after all array's in lua start ar 1 not 0 so using (0) as a parameter kinda breaks the rules
