Oops, you are right: I misread. I though you was recreating the listview,
sorry for he confusion!
Also, "reattach the listview's parent-container" simply means what you
already do by:
target.add(RecentlyViewedItemsPanel.this.get("itemContainer"));
(this is because it is not possible to reattach the listview directly but
you already knew that)
Well, as I said earlier, maybe is it a cookie/IO issue. I mean: the fact of
deleting and persisting changes in the cookie may be IO-asynchronous and
then the model is updated before changes are persisted...
I hope someone can help you on that subject...
Best regards,
Sebastien.
