I retrieve some event.data from a web service that i'm not able to exploit.
A trace(event.data); gives me this : [object Object]. I can't find a way to extract that, to know what is inside before casting it to something, and i find nothing in the documentation API. event.data.className is undefined.
This looks like a stupid general beginner question...
This will alert out everything that's within event.data into a single string. The format won't be pretty but it'll most likely tell you everything you need to know that's inside of that object.
