Re: [flexcoders]Can't convert XML to ArrayCollection in AS3
What if you were to create ac like this:
var ac:ArrayCollection = new ArrayCollection(myXML.menu as Array);
The way that I interpret the ArrayCollection (or XMLListCollection)
source property rule is that you must use the methods to modify
the source and don't rely on it's setter method (setting the
property directly as in ac.source = myXML.menu as Array;).
source
property
source:Array [read-write]
The source of data in the ArrayCollection. The ArrayCollection
object does not represent any changes that you make directly to the
source array. Always use the ICollectionView or IList methods to
modify the collection.
Let me know if that works.

Re: [flexcoders]Can't convert XML to ArrayCollection in AS3
XMLListCollection has a toArray() method.
So maybe:
var ac:ArrayCollection = new ArrayCollection(new
XMLListCollection(xml.menuas XMLList).toArray());
it might be a bit nicer written on more than one line, but you get the idea.
