Javascript -> Flash throwing “Error calling method on NPObject”

Question

I\'m trying to call a Flash (AS3) function from Javascript. When the code runs, I get the error \"Error: uncaught exception: Error calling method on NPObject!\" From my day\'s

Answer 1

I found that by installing the Debugging version of the flash player from Adobe's site, I'd get a dialog box with the actual flash exception in it instead of the NPObject error, so this might be a helpful first step in figuring out what's actually going on.

In my case it looks like somehow, there is an incorrect number of arguments getting passed, and I'm not sure how this is happening (intermittently), but that's for another question. :)
