下面代码为HierarchicalDataForGroupedColumns.as文件中的代码，注意此文件建立的是as文件而不是as类文件。

[Bindable] public var dpHierarchy:ArrayCollection = new ArrayCollection([ {Region:"Southwest",Territory:"Arizona",? Territory_Rep:"Barbara Jennings",? Revenues:{Actual:38865,Estimate:40000,Territory_Rep:"Barbara Jennings",Territory:"Arizona"}},?????????????????{Region:"Southwest",? Territory_Rep:"Dana Binn",? Revenues:{Actual:29885,Estimate:30000,Territory:"Central California",? Territory_Rep:"Joe Smith",? Revenues:{Actual:29134,Territory:"Nevada",? Territory_Rep:"Bethany Pittman",? Revenues:{Actual:52888,Estimate:45000,Territory:"Northern California",? Territory_Rep:"Lauren Ipsum",? Revenues:{Actual:38805,? Territory_Rep:"T.R. Smith",?
