Implement ITreeDataDescriptor and set the tree's data descriptor
thus every time you open a node you call the getChildren function of your
data descriptor
a simple example
internal class ReferenceDataDescriptor implements ITreeDataDescriptor
{
private var __delegate:QueryBuilderTreeDelegate;
public function
ReferenceDataDescriptor(delegate:QueryBuilderTreeDelegate)
{
__delegate = delegate;
}
public function getChildren(node:Object,
model:Object=null):ICollectionView
{
var referenceDataDelegate:ReferenceDataBrowserDelegate =
__delegate.referenceDataDelegate
var gt:GenericTable = GenericTable....
....
}
then store the data i get back in a hash table
so hash['a\b'] = ArraycCOlleciton
for local caching.
