Description
Originally by Les_1
When using bean container as data source for grid and replacing one item in container with another, changes in new item are not visible in grid.
But changes in old, no longer present in container item are visible in grid.
This started to happen after I started using Vaadin 7.6.4. In 7.5 it was working fine.
Attached sample code was working properly in version 7.5. After changing version to 7.6.4 button with label "ACTION4" is no longer changing data in grid row.

Research direction
Start by reproducing the attached sample with a bean container as the Grid data source, comparing Vaadin 7.5 with 7.6.4. Replace one container item and verify whether the new item's changes appear while changes from the old item remain visible; done means the Grid reflects the replacement correctly in the affected version.
