hiya… i am attempting to add “unknown” properties/variables to the MX Class:XMLConnector. I need this so that i can pass more information to the object that will be used when the result method is called.

here is how i am doing it:  
var \_me:String;  
for(\_me in args){  
$xml. **proto** [\_me] = args[\_me];  
}

this is working great, until i have more then one call to the function which makes this happen. then i find that the last of the calls overrights all of the values…

here is my question: are variables added to an object using **proto** static? if so, how can i make them instance?

is there any other way to add a variable to a class, while still using typed var statments?
