Hi.
As I see it's impossible to call Javascript function from
flash in modal dialog (opened with showModalDialog), neither with
getURL nor with ExternalInterface.call.
The only solution I found (in my case it's enough, I only
need to refresh some DIV content in the page from flash) is to
catch error in the modal dialog (Javascript window.onerror) and
then do some operations.
I'm intereseted: is this for security reason on Win XP SP2? I
didn't found any solution, but is there any?
