In your model, replace type: 'datetime'
by type: 'date'
, and remove the dateFormat
, which is the expected data format (or configure it to match your response date format). The display format is the one you've configured in your grid, and that you should configure in your date field.
This way, the response data will be parsed to a Date
object by the model, and this date object will be correctly interpreted both by the grid and the fields.
