Question

I have a cell table with an async data provider. If I update the data via the data provider the table renders the new data correctly but the selection model still holds onto and returns old objects.

Any ideas how to refresh the selection model?

I think you should make your SelectionModel work with different instance of the same “logical” object using the appropriate ProvidesKey. For instance, you could use ProvidesKey that calls getId on the object, so that two objects with the same such ID would be considered equal; so even if the SelectionModel holds onto the old object, it can still answer “yes, it’s selected” when you give it the new object.
FYI, this is exactly what the EntityProxyKeyProvider does (using the stableId of the proxy). And the SimpleKeyProvider, used by default when you don’t specify one, uses the object itself as its key.
