How to refresh a single row in a ListGrid

[jay.l.fisher]

Is there any way to request a single record in a ListGrid to be refreshed, like it would be if via the cache-synch fetch if the record was updated, but without actually updating it. I know I can invalidate the cache for the ListGrid and force a re-fetch of the entire grid contents, but can I request a refresh of a single record without reloading the entire grid?

Use DataSource.updateCaches() to broad an update to all components. If you already have the update data in hand, just make an "update" DSResponse from it, otherwise, use DataSource.fetchData() to fetch a new copy of the row, and build an "update" DSResponse from that.
