After getting userIds, you can use them for reassign, route or set any parameter etc. again using managed bean.

Groovy in ADF

Groovy is an agile, dynamic language for the Java platform, defined as JSR 241. It has many features that were inspired by languages such as Python, Ruby, and Smalltalk, making them available to Java developers with a Java-like syntax. It interoperates seamlessly with any Java class, and can be compiled and interpreted without disturbing normal operations.[Read More]

Introduction to ADF Task Flow

Task Flows at the Heart of Oracle ADF
There is nothing more important than understanding task flow-oriented design and architecture when developing Oracle ADF applications

ADF controller supports task flows. Supporting task flows helps us to break our complex web application into smaller reusable flows. The task flows are simple XML files. Each of the pages in the task flow is added as a view activity and the control flows between the pages. The components in the task flows are called as activities and each of the control flows will have an outcome to define the navigation.

Develop User Interface Services – Not Pages
Steven Davelaar, "Building Highly Reusable Task Flows"

There are two types of task flows in ADF

Unbounded Task Flow

Unbounded task flows are designed to handle navigation between pages which do not necessarily follow any specific entry point or exit point. For example, consider the pages linked through the toolbar menu in an application. An end user can select any menu option that he or she likes, or the person can even type the URL directly in the browser for viewing the page and can exit from the page or switch to a new page at any point in time. The navigation model for such pages (unbounded view) is defined using unbounded task flow. Unbounded task flow defines navigation for unbounded views in a Fusion web application.

Bounded Task Flow

The bounded task flow is primarily designed to implement reusable navigation cases with definite entry and exit points. A bounded task flow contains its own set of control flow rules, activities, and managed beans.

ADF Business Components

ADF Business Component is a Java and XML based framework for developing.
  • Business logic, including validation and default logic
  • Queries
  • Transaction handling
  • Data access
It does not create a user interface, but is a pure encapsulation of business logic that communicates with a separate client application, which handles user interaction.

Using ADF BC is the simplest way to design data-aware applications with JDeveloper.
