Hello, guys. Thank you for this thread.
Alexander, I have updated your jsfiddle: http://jsfiddle.net/313t2crx/
I have added "editable: true" and "batch:true" to the dataSource.
You said "Pressing the save button in any of the detail forms updates the corresponding data item which again forces the grid to refresh." but changing the value INSIDE THE COLUMN cause the dataItem update as well (because we see the new value in the detail row as well) but doesn't close the detail row. So my questions are:
1. What difference between input with data-bind in CELL and input with data-bind in DETAIL?
2. How to make the input in the DETAIL works the same way as the CELL one (doesn't close the detail row)
