To create an event listener on a parent component programmatically, the developer should use the following line of code:

this.template.addEventListener(‘notification’, this.handleNotification);

This line of code adds an event listener to the template element of the parent component, which is the root element that contains all the child elements. The event listener listens for an event named ‘notification’, which is a custom event that can be dispatched by any child component. The event listener invokes a method named handleNotification, which is an arrow function defined in the parent component class. The handleNotification method receives the event object as a parameter and can perform any logic based on the event data. The other lines of code are either incorrect or incomplete.

In general best practices for tax implementation in systems like Salesforce B2B Commerce, previous tax entries are usually preserved or saved before any recalculation is performed. This ensures that there is a record of the original tax calculations before any modifications, which can be crucial for auditing, historical data integrity, and in case the new tax calculation needs to be rolled back for any reason.

 Executing dynamic SOQL inside a without sharing class with a bind variable from PageReference.getParameters(), PageReference.getCookies(), or cc_RemoteActionContext class will open up a major security hole because these sources of input are not sanitized and can be manipulated by malicious users to inject SOQL queries that bypass the sharing rules and access data that they are not supposed to see. For example, a user can modify the URL parameters or cookies to include a SOQL query that returns sensitive data from the database. To prevent this, it is recommended to use static SOQL or escape the bind variables before executing dynamic SOQL.

The next step that the developer should do after suspecting that recent edits made to a checkout flow have created a defect and having data points available to use as inputs in reproducing the scenario is to open the flow, select Debug, provide the Input values, and select Run. A flow is a type of application that automates a business process by collecting data and performing actions in Salesforce or an external system. A flow can be used to customize the checkout process in the storefront by defining the steps and logic that are executed when a customer places an order. A flow can be edited or modified using Flow Builder, a point-and-click tool that allows developers to create and manage flows. Flow Builder also provides debugging and testing tools that allow developers to run and troubleshoot flows before deploying them. To debug or test a flow, the developer can open the flow in Flow Builder, select Debug from the toolbar, provide the Input values for the flow variables, and select Run. This will execute the flow in debug mode, which simulates how the flow runs in the org with real data. The developer can use debug mode to verify if the flow works as expected or if there are any errors or issues with the flow logic or actions. Open the flow, select Attach to Live Session, provide the session ID, and select Attach is not a valid next step, asit is not a feature or option available in Flow Builder or Salesforce CLI. Attach to Live Session is a feature that allows developers to attach a debugger to a running Apex session and inspect the state of the code execution. Open the flow, select Debug with Inputs, provide the Input values, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Debug with Inputs is a feature that allows developers to debug an Apex class or trigger with predefined input values and breakpoints. Open the flow, select Debug, provide the session ID for replay, and select Run is not a valid next step either, as it is not a feature or option available in Flow Builder or Salesforce CLI. Replay is a feature that allows developers to replay an Apex log file and inspect the state of the code execution at each line.
