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

Thu Aug 20 15:10:42 PDT 2009

Her'es another question:

it seems like:

someView.getMCRref().innerHTML

works as well as

someView.sprite.getMCRef().innerHTML

And looking into the code I discover, that LaszloView#getMCRef just  
does:
function getMCRef () :* { return this.sprite.getMCRef(); }
Any reason for doubling that behavior?
