Persist selection on tree viewer on restart of application using memento [message #1275666]

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

You have to also save and restore the collapsed state of your tree. Furthermore, the saved selection is no longer the object that is in the new tree.
