The following topics introduce the new and changed features of Oracle JDeveloper and Oracle Application Development Framework (Oracle ADF) and other significant changes, which are described in this guide. This document is the new edition of the document formerly titled Fusion Developer's Guide for Oracle Application Development Framework.
Oracle Fusion Middleware Release 12c (12.1.2) of Oracle JDeveloper and Oracle Application Development Framework (Oracle ADF) includes the following new and changed development features, which are described in this guide.
ADF Business Components
New offline database option, which supports using an offline database as the database object provider for the data model project. This feature lets you work in a disconnected fashion and pick up database changes when are ready. See Section 3.2.4, "How to Change the Data Model Project to Work With Offline Database Objects."
New row finders feature, which can be used to locate specific rows in a view object row set. The row finder is similar to query by example searches, and does not rely on a row key attribute to locate specific rows. See Section 5.11, "Working with Row Finders" and Section 6.2.8, "How to Find Rows of a Master View Object Using Row Finders."
Revised Query page in the view object overview editor, which makes it easier to manage query bind parameters and avoid the unreferenced bind variable SQL exception. See Section 5.10.2, "How to Add WHERE Clause Bind Variables to a View Object Definition."
New View Criteria page in the view object overview editor to show view criteria bind variables, which makes it easier to avoid the unreferenced bind variable SQL exception. See Section 5.10.1, "How to Add View Criteria Bind Variables to a View Object Definition."
New multiple required view criteria feature, which allows you to prevent view criteria that you apply to a view object instance in the application module data model from being unapplied whenever your application invokes the view criteria API. See Section 22.214.171.124, "Customizing a View Object Instance that You Add to an Application Module."
jbo.ampool.connection_threshold application module configuration property, which specifies the maximum number of connections that application module in all application module pools combined may hold onto without releasing back to the connection pool upon checkin. See Section 50.2.7, "What You May Need to Know About Application Module Pool Parameters."
Removed documentation related to the deprecated EJB Session Bean-enabled application modules, which means it is no longer possible to create or run EJB Session Bean-enabled application modules in JDeveloper. For ways to migrate existing EJB Session Bean-enabled application modules, see Section 13.1.1, "Application Module Use Cases and Examples."
ADF Data Visualization components
New ADF Data Visualization components:
sunburst. See Chapter 39, "Creating Databound Hierarchy Viewer, Treemap, and Sunburst Components."
New active data support for these additional ADF Faces components:
treemap. See Section 47.1.1, "Active Data Service Use Cases and Examples."
Revised user interface for the Oracle Diagnostic Log Analyzer, which makes it easier to view ADF log messages. See Section 42.6, "Using the ADF Logger."
oracle.adfdiagnostics logger, which enables ADF logging using a single logger. See Section 42.6.2, "How to Create an Oracle ADF Debugging Configuration."
New JDeveloper window names, context menu options, and other UI changes in JDeveloper are reflected in all chapters of this guide..
ADF Faces button and link components are now consolidated into the
af:link components. All code examples in the book have been updated to reflect these new components.
For Release 12c (12.1.2), this document has been updated in several ways. Following are the sections that have been added or changed.
Updated images of the sample application that appear throughout this guide with images that reflect the new Summit sample applications for Oracle ADF. See Chapter 2, "Introduction to the ADF Sample Application."
Updated sample code that appears throughout this guide with samples that reflect the new Summit sample applications for Oracle ADF. See Chapter 2, "Introduction to the ADF Sample Application."

See Section 4.14.9, "What You May Need to Know About Custom Entity Object Methods" and Section 10.1.3.4, "Avoid Creating Dependencies on Parent Application Module Types."
Moved sections describing how to create master-detail relationships to a new chapter. See Chapter 6, "Defining Master-Detail Related View Objects."
Added a new section to describe how to create inline view criteria to reference detail attributes in a master-detail view object hierarchy. See Section 6.4, "Working with Master-Detail Related View Objects in View Criteria."

Added a new section to describe how you can now specify a bounded task flow to render in an ADF region as an alternative to bounded task flows that users may not be able to access due to not having the required security permissions. You specify the alternative bounded task flow as a value for the
unauthorized-region-taskflow element in the
adf-config.xml file. See Section 23.12, "Handling Access to Secured Task Flows by Unauthorized Users."

Added a new section to describe the interactions that occur when you configure two bounded task flows to share a transaction to save connection resources and stop the transaction if the called bounded task flow cannot join the transaction of the calling bounded task flow. See Section 188.8.131.52, "Guaranteeing a Called Bounded Task Joins an Existing Transaction."
Added a new section to describe the interactions that occur when you call a bounded task flow that joins the transaction of the calling bounded task flow if one exists and, if not, creates its own transaction. See Section 184.108.40.206, "Using an Existing Transaction if Possible."
Added a new section that describes the configuration changes to make if you want to have separate root application modules connect to different data sources within the same ADF Model project.
