I am trying to write Celltree with below requirement.
1) Populate tree based user definded class/datastructure.
2) User will able to edit leaf node. While editing he will get list of
available values(SuggestBox). Leaf lavel is composite cell having images
and InputTextCell.
3) User will click save button. It will create class object again created
with updated data from tree.
I am able to implement first 2 steps. but I am not able to get the updated
data from tree. I created data provider structure similar to class. When I
click save I get old values only.
Kindly suggest the changes which I need to do. Please find the aatched code.
