In your TreeViewModel for CellTree you have to have to implement TreeViewModel.getNodeInfo(..). A default implementation of NodeInfo is DefaultNodeInfo which takes a SelectionModel in its constructor.

thank you so much for replay, Actually i used Tree. Is it i need to
use CellTree to get support for multiselection?

You don't have to. You could also write your own class that defines some logic how to select items in a Tree. 

If you plan to display lots of data in a Tree then you should switch to CellTree as its a lot faster for large data sets.

Thank you so much Jens, appreciate your timely help. I am displaying
lot of data on tree, maybe I need to reconsider to use Tree.
