I am using memento for persisting views.
I am not able to persist selection on tree viewer I have the following code in save state

IStructuredSelection selection = (IStructuredSelection) viewer.getSelection()
Then I am storing this as selection.toString in memento

While restoring
IMemento storedSelection = memento.getChild("StoredSelection");
viewer.setSelection(new structured selection (selection) );

When setting selection on tree viewer I am getting proper value
but in selection change event it is telling empty selection due to which no selection is retained on tree

I am right now trying for single selection of tree
I would like to do tdo for multiple selections also

Please provide working sample code
