Re: contacting the browser through Flash



I've yet to create a widget that uses Flash, but take a look at this:

ExternalInterface

Its a better way to talk to javascript

OK - let's set all the java vs. flash arguments aside for a moment :)

We are using Flash in a widget. With OnRollover, our clicks work
great to control the remote flash file. No sandbox violations, it's
great.

Until we tried to link to an external URL.

The GetURL AS command only replaced the height and width parameters
of the widget with the Webpage on the dashboard (which is kinda cool,
though I haven't thought how to make that work in a useful way).

We followed a path of experimentation between javascript and flash,
finally settling on the Flash ExternalInterface.call to send a url to
a HTML javascript function that runs a widget.openURL like so:

function showFlashURL(urltoopen)
{
        alert(urltoopen);
        widget.openURL(urltoopen);
}

Now, we've tripped over the edge of the sandbox. Clicking a URL in a
widget where the Flash is remote, the HTML is local, and the command
fires back through the HTML to throw a Flash security violation.

If anyone can help here, it would be so appreciated, there may be a
reward involved. This is obviously a critical function that needs to
be solved. And we're stuck.

Thanks,

Michael
