DataProvider refreshAll effect is too intrusive

If a user is scrolling a grid and a refreshAll is called, the grid is emptied and the use loses its scroll position. Also, if there are component-renderers they disappear for a moment while the grid is refreshed.

This is quite intrusive, especially if the refresh is coming from a push event and the user isn't aware of it.

Calling refreshAll should be smoother, e.g.

• add new items coming from the refresh
• remove items missing from the refresh
• update items already present on the list

This way the list isn't emptied and entirely reconstructed, which could be quite intrusive for the user (read: our users are lamenting this quite often).

Any update or workaround for this? How to remove a treegrid root item without losing scroll postion?
