I am using a combobox within a datatable, and when I hit the tab key, the value I selected does not get saved.
For example, go to the snippet and select a year under the “released” column. Hit tab, and the year that was selected was not saved.
As you can see, value is not set until the editor closes. It is the default logic of a combo editor. When you move keys to select items in the popup, the input still houses the old value.
You can overcome it with the help of an onBeforeEditStop handler to tell the editor its current value from the selected option in the popup.
