LiveEdit not working for iframe (like facebook?)

Hi all, I'm using WebStorm 7, and I am very happy about it.
I'mt trying to use the liveedti with a page inside an iframe, like as following:

apache_http
/pippo
     index.html

/pluto
     page.html
Index.html as an <iframe sro="/pluto/page.html> (this is a simplification of a facebook apps)

I'm working only on css and dom elements in page.html, bu I need to load the page in the iframe of pippo/index.html
How do I set up the debugger to debug and use liveEdit in this situation? It seems that the liveedit doesn't work in this situation...li
