I'm building a quite large Flex application as our administration tools and I need build in documentation functionality. I want this documentation to be like a wiki and as we're using Google apps I though I'd use Google sites to host the wiki pages (why reinvet the weel...).
To include the wiki page in Flex I'm using the http://code.google.com/p/flex-iframe/ component that uses an iframe.
The problem is that it seem that google site uses some form of iframe javascript breakout script and that when i load the iframe the entire page is loaded with the wiki page.
You could try an anti-frame-busting script like the one on Jeff's site. Normally I wouldn't recommend that, but it seems like you have a legitimate need for it here.
