You've declared that the instance obj should be bindable, but that
doesn't make the properties on the class Object bindable. What you
can do is create a class for the object you want to pass your custom
component and add the bindable metadata tag to the properties you want
to bind on.
You can also add the metadata tag to the class definition. That will
make all of the properties of the class bindable.
package
{
[Bindable]
public class Obj extends Object
{
public function Obj()
{
super();
}
public var str:String = "";
}
}
