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" Tracy ________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Ralf Bokelberg Sent: Tuesday, March 13, 2007 10:59 AM To: flexcoders@yahoogroups.com 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 Ralf.

I don't know how to to this.
