Answer: B
Explanation:
For the data to be passed back to the Aura component, all properties of the Apex class that are intended to be accessed from the component need to be annotated with @AuraEnabled. Without this annotation, the Aura framework cannot serialize the properties to send them to the front end.References: Aura Components Developer Guide - AuraEnabled Annotation

NEW QUESTION # 111
A company has a custom component that allows users to search for records of a certain object type by invoking an Apex Controller that returns a list of results based on the user's input. When the search is completed, a searchComplete event is fired, with the results put in a results attribute of the event. The component is designed to be used within other components and may appear on a single page more than once.
What is the optimal code that should be added to fire the event when the search has completed?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
The optimal code that should be added to fire the event when the search has completed is Option D.
This option uses the $A.get("e.c:searchComplete") method to get the event definition, the setParams() method to set the results attribute, and the fire() method to fire the event. The option also uses the cmp.getEvent("searchComplete") method to get the event definition, which is equivalent to the $A.get() method. Option A is incorrect, as it uses the $A.createComponent() method, which is used to create a component dynamically, not an event. Option B is incorrect, as it uses the $A.eventService.newEvent() method, which is deprecated and should not be used. Option C is incorrect, as it uses the $A.enqueueAction() method, which is used to invoke an Apex controller method, not an event. Reference: [Create and Fire Events], [Lightning Components Developer Guide]

- A. Use lazy loading to load the data on demand, instead of in the controller's constructor.
- B. Use an <apex:actionPollar) in the page to load all of the data asynchronously.

- D. Use the transient keyword for the List variables used in the custom controller.
Answer: A
