Flex ArrayCollection CollectionEvent dispatching class changes

Lets say you have a class:


[ArrayElementType("com.my.AwesomeClass")]
private var myAC:ArrayCollection = new ArrayCollection();


your class is such that sometimes changing a property in AwesomeClass doesn't
make myAC dispatch CollectionEvent.COLLECTION_CHANGE. An example changing the
property awesomeClass.foo.x.

To tell myAC that an item is changed use ArrayCollection's itemUpdated method after changing an element in the ArrayCollection.


myAC.itemUpdated(awesomeClass);
