[haXe] conditionnal if else

[filt3r at free.fr]

hmmm, ok thanks for the quick answer ;)
I won't cast it to Button, I'll do the 2nd case, it's also fast.
But, as I said, writing "var b : Button..." I thought that it will be
automatically casted, especially when both extends Button (= the same type) :(
That's ok, I just wanted to know, it's a bit confusing me.
Thanks for your answer,
Michel
