RE: [flexcoders] Objects and arrays as treeview datasource
The API is listed here: http://livedocs.macromedia.com/labs/1/flex20beta2/langref/mx/controls/treeClasses/ITreeDataDescriptor.html The most important ones are isBranch and getChildren. In B2 be aware that isBranch and getChildren can be passed null in which case you should just return false and null respectively. If you dont need drag and drop just have addChildAt and removeChildAt return false. getChildren should just return an ArrayCollectoin that contains the array pointed to by the node property. isBranch would return true if node != null node.length 0 I guess.

RE: [flexcoders] Objects and arrays as treeview datasource
Since the children are named node and not children the default data descriptor isnt going to work. You probably need to write a quick ITreeDataDescriptor implementation that will return the right children property/collection.
