[flexcoders] How to save a sharedobject value based on a parameter name??

[tjcox1969]

I want to have a function that one can call to save a name/value into
the clientside SharedObject.

The Flex doc has the example like this:

     var my_so:SharedObject = SharedObject.getLocal("superfoo");
     my_so.data.itemNumbers = items_array;
     my_so.data.adminPrivileges = currentUserIsAdmin;
     my_so.data.userName = currentUserName;


My issue is that I don't want to hard code the name of the cookie.  So
in the above example, I don't want to hardcode "itemNumbers".

Here is what I want to do:

public function saveCookie(key:String, value:String):void {
     var my_so:SharedObject = SharedObject.getLocal("superfoo");
     my_so.data.key = value;
}

The problem is that "data.key" is not evaluated to its real parameter
value and the cookie is saved as the hard coded "key" string.

Any ideas?  Thanks!
