This is a different thing though. For example, what if the source object doesn't exist at the time you are assigning the reference because it is retrieved from the backend. What if your reference comes from an external configuration file? I guess both methods have valid uses.

You are asking for trouble doing this... Just do as I suggested earlier. When you set the source set it to the object and have a string that is the name of the property that is the real target. var source:Object; var property:String; then when you access that porperty you do it like this... source[property]; simple. --- In [email protected] <flexcoders%40yahoogroups.com>, "Ralf Bokelberg" <[EMAIL PROTECTED]> wrote: > > In the older flash days we had eval to achieve this.
