I need to creare N instances of a class without having to define those objects on context.

think about this:
for (var i:int=0;i new MyAutowiringClass();
}
if MyAutoWiringClass extends AutowiringObjectBase and has some properties marked as [Autowired] those properties are injected automatically and I did not write 1 line of xml on the context.

its also possible to use the [Autowired] metadata on non-visual objects. Just annotate the properties in your class, and only define your object in the XML like this:

when you instantiate the obhect through the container liek this:
var o:myClass = applicationContext,getObject(“myObject”);

your properties will have been injected.
