The updateView method will be called when any value in the property bag has changed. This includes field values, data-sets, global values such as container height and width, offline status, component metadata values such as label, visible, etc.
Set the value of the field component to the raw value from the configured field.
Note: webAPI.retrieveMultipleRecords retrieves a collection of entity records.
