[flexcoders] Binding behaviour

[geckko]

Hi all,

I'm trying to duplicate one object but when i modify the "master" object
the child object is modified too. My code is something similar to this

private function cloneLeaf():CallMonitoringLeaf{
            var obj:CallMonitoringLeaf = new CallMonitoringLeaf();
            obj.optionCallMonitoring = optionCallMonitoring;
            obj.nodesSelected = nodesSelected;
            obj.dataCallMonitoring = dataCallMonitoring;
            obj.nodeName = nodeName;
            return obj;
}

But when i modify nodeName (for example) in the object that i use to
duplicate (master object), the child object modifies its name too. Is
there any way to avoid this behaviour?

Thanks in advance
