QUESTION: 219 Exam Topic: Extend the User Experience Questions

A multinational company requires that all phone numbers be standardized as country code + area code + phone number.

The application design team decides that a custom Power Apps component framework (PCF) control should be used to prompt users for an area code and to correctly format the phone number.

You need to get the list of valid area codes when a contact record is opened and before the user enters a new phone number.

You need to get the list of valid area codes when a contact record is opened and before the user enters a new phone number.

In which function should you call webAPI.retrieveMultipleRecords?

updateView
notifyOutputChanged
getOutputs

Answer(s): A

Explanation:

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.

Incorrect Answers:
notifyOutputChanged is a callback method to alert the framework that the control has new outputs ready to be retrieved asynchronously.

getOutputs is called by the framework prior to a component receiving the new data. Returns an object based on nomenclature defined in manifest, expecting objects[s] for the property marked as bound.

Problem patterns: Web-use-async
There are multiple ways to interact with the server or request resources. Common approaches that allow for synchronous communications include the following (These scenarios should be avoided.):
-Usage of the XMLHttpRequest object passing in false for the value of the async parameter for the open function call
var requestXhr = new XMLHttpRequest();

// Explicitly setting the async parameter to false or supplying a variable with a value of false will force this as a synchronous call.
requestXhr.open('GET', '/test/test.txt', false);

Box 2: No

Box 3: No
No debugger statement in the code, so web-remove-debug-script (avoid including debug script in non- development environments) does not apply.
