I've created an example that reproduces the issue some of the time. This issue does not occur all the time but seems to be related to using the mouse button and update button. Hitting enter to save seems to always work. At first I thought it was my code (validation, etc) but I've narrowed it down to a simple example that still is an example of the issue.
I've previously had hacks in place to have custom buttons that call $(document.activeElement).blur() before calling a grid update method but even that was problematic.
Dojo example: http://dojo.telerik.com/oWoBu
Screencast showing the issue: http://screencast.com/t/lsmHjMqc
In the screencast the first two attempts succeed but the third attempt shows how the data isn't saved.
