I've got a bit further with this and have got my dataDescriptor class
working ok now.
To load new data when I expand a branch on the tree I need to throw am
ItemPendingError which the Tree component will catch. I am unsure how to do
this however.
This code:
public function getChildren(node:Object,
model:Object=null):ICollectionView
{
if(node.catsLoaded == -1){
return new ArrayCollection(node.children);
} else {
throw new ItemPendingError("data pending");
}
}
Simply halts the application and I get lots of red text in the output
window. It doesn't seem to get caught by the tree, which should add some
item responders.
How can I throw the error at the Tree if you se what I mean.
Thanks, I hope someone can help with this.
