By default, when an error has been returned from the controller on inline Task edit, the edited value will be reverted to the last valid value, without the need to cal the DataSource read()
method. Here you will find a small Dojo sample
, that demonstrates the above. You will notice, that the Update
URL is not a correct endpoint, so a 404 error is returned to the client.
Thus, in case of any issues with the model state on the server, I would suggest you to return an error from the controller action, so the value would be reset.
