Have you verified this line below? It raises doubts: var bigCollection:ArrayCollection = data.result.myBigList as ArrayCollection; //I am reading an xml file.
First, XML will only yield an XMLList and you cannot cast an XMLList to an ArrayCollection. I suspect you may not have xml as you think, but instead a nested object structure. It depends on how you are getting your data. If that is so, it is not a good way to do it. Have you set your resultFormat="e4x"? If you are getting XML from the server, why not use XMLListCollection? If you do not want to use that, you should convert your XMLList into an ArrayCollection of strongly typed data objects. This is a manual process of looping over the XMLList and building each object and then adding it to the AC.
