Today I had almost the same issue.. :-) It seems that browsing the model of the CellTree is almost impossible from the side of a SelectionModel or a DefaultSelectionEventManager. I inherited from DefaultSelectionEventManager and tried to override doMultiSelection(..) but from that method I could not access the tree data as it is hidden by the HasData<T> interface. When debugging the instance of this interface is a CellTreeNodeView$NodeCellList but is a private inner class that cannot be accessed.. :-(
