best way to implement this wait functionality

[phil.swenson]

I have this function that returns an instance to a flash widget:

function getFlashInstance() {
if (navigator.appName.indexOf("Microsoft") != -1) {
return window[FLASH_MOVIE_NAME]
}
else {
return document[FLASH_MOVIE_NAME];
}
}

The problem is if my flash widget isn't loaded yet I get an undefined
object...

I have a function that gets called when the flash object is registered
(lineChartLoaded()). What I want is for the getFlashInstance to "wait"
until the lineChartLoaded function is called and then return the
object.

Also note that I really can't just trigger this whole thing off the
lineChartLoaded() function because there is server side state I'm
waiting on too.

Any suggestions?

window.onload = someFunction;

And someFunction starts the whole process. The only way to know for sure
that an object is loaded is either the onload of the object or the
onload of the window.
