timgerr, You have to convert a table list, lft and rgt nested set approach, to an hierarchical model in server side. Unfortunately, the Flex DataDescriptionDefault only work in a model of array of array with 'chidren' field.
As soon as I have time, I intend to develop a class that implements ITreeDataDescriptor. This class will work on nested set approach (MPTT) and pageable skill.
