Introduction

Welcome to the Second part of the ADF Task Flow series. In the previous part, we discussed the basics of ADF Task Flow, including the View Activity and the Router Activity. In this article, we will Delve deeper into the Task Flow concepts and explore how to add and update records in ADF Task Flow. We will cover various topics such as creating activities, adding navigations, using wildcard control flow rules, and more. So let's jump right in!

Overview of ADF Task Flow

Before we dive into the details, let's have a quick overview of ADF Task Flow. ADF Task Flow is a framework provided by Oracle Application Development Framework (ADF) for creating and managing user navigation in your application. It allows you to define the flow of pages and activities in an application, making it easy to Create complex navigation scenarios and reuse them across multiple pages.

View Activity and Router Activity

In the first part, we discussed the View Activity and the Router Activity. The View Activity is responsible for rendering the user interface, while the Router Activity is used to determine the next activity Based on a set of conditions or rules. These activities play a crucial role in defining the flow of your application.

Method Call Activity

We also explored the Method Call Activity, which allows You to call a method defined in your application from within the task flow. This activity is useful when you need to perform some specific logic or operations before moving to the next activity.

Adding and Updating Records

Now, let's move on to the main topic of this article: adding and updating records in ADF Task Flow. This functionality is essential when dealing with data manipulation in your application. We will start by creating a new activity for adding records and then proceed to update existing records.

Creating a New Activity

To add records, we need to create a new activity called the "Review Activity." This activity will serve as a page where users can enter the details of the new record. We will add this activity to the department's view control in the data control section.

Adding Navigations

Since we will be updating records in this task flow, we need to define the navigations. Navigations help us move between different activities and perform various operations. We will add navigations to the department's table and configure them to perform the desired actions.

Creating Insert and Update Operations

In order to insert and update records, we will use the built-in operations provided by the data control section. We will create the "Create Insert" operation for adding records and the "Update" operation for updating existing records. These operations will be called from the department's view navigation.

Adding Buttons to the Department Table

To facilitate Record creation and update, we need to add buttons to the department's table. We will add two buttons: one for adding records and one for updating records. These buttons will trigger the respective operations and perform the necessary actions.

Adding a Back Button to the Update Page

To ensure a seamless user experience, we will add a back button to the update page. This button will allow users to navigate back to the department's page after performing the update. We will configure the action of the button to return to the department's page and display a success message.

Understanding Relative Activity

In addition to adding and updating records, we will also explore the concept of relative activity. Suppose you have a Facebook page with multiple actions and reactions. In ADF Task Flow, you can define relative activities to control the flow of actions and reactions based on the user's input.

Using Wildcard Control Flow Rule

To efficiently handle multiple views and actions, we can use wildcard control flow rules. These rules allow us to control the flow of activities using a star map pattern. By defining a wildcard control flow rule, we can ensure that any activity calling a specific action follows a predefined path.

Creating a Task Flow Template

Task flow templates provide a way to reuse common navigation Patterns across multiple task flows. We will explore how to create a task flow template and define navigation within the template. By utilizing task flow templates, we can simplify and standardize our task flow design.

Exploring Task Flow Return Activity

The task flow return activity is used to return from a child task flow to the parent task flow. We will discuss how the task flow return activity works and when to use it. Additionally, we will explore alternatives to task flow return activity for better control over task flow navigation.

Showing Employees on a Popup Web Page

By default, ADF Task Flow shows the employee details on the same web page. However, there may be a requirement to show the employee details on a popup web page. We will discuss how to accomplish this by using window positioning and inline document configuration.

Increasing Width of Department Counting

Sometimes, the default width of certain components in ADF Task Flow may not be sufficient. We will learn how to increase the width of the department counting component to ensure better visibility and user experience.

In this article, we have covered various aspects of ADF Task Flow, from basic concepts to advanced features. By following the step-by-step guide, you will be able to create and manage task flows effectively, adding and updating records, and delivering a seamless user experience. So let's start exploring ADF Task Flow in more Detail and take your application development to the next level!
