[Laszlo-dev] Modifying someView.sprite.__LZdiv.innerHTML

Thu Aug 20 15:02:41 PDT 2009

There is the view.getMCRef() method which returns a reference to the 
view's div (or movieclip if you're in Flash).  It's expedient, but 
dangerous - so your mileage may vary!

I filed an improvement request to give this method a better name:
