I think if .property is a string or other "primitive", you cannot pass a
reference to it but will always get a copy of the data.
Instead, why not pass a reference to the entire object, and access
.property within the consuming coomponent?
<comp: SomeCustomComponent source="{model.someObject.currentObject}" />
class SomeCustomComponent{
public var source:Object; //THIS SHOULD BE TYPED SPECIFICALLY
if possible
source.property = "mystring"; //shold update the property on the
"model.someObject.currentObject"

Subject: Re: [flexcoders] Re: Passing an object reference as a property
In the older flash days we had eval to achieve this. Now you need to
implement it on your own.
Split the string at the dots, start from a top object and dereference
one property after the other until you get to the last part of the
string.
Cheers

In simple terms I think what kevin wants to do is:
var x;
var myvar;
var value;
function A(varname, value) {
varname = value)
}
myvar = "x";
value = 42;
A(myvar, value);
The required result is that the variable x should contain the value 42.
I don't know how to to this.
