What is PageFlowScope in ADF?

What is PageFlowScope in ADF?

PageFlowScope is used to share the data between activities in the task flow. Also input parameter and output parameters of the task flow are stored in the pageflow scope.

How do you pass parameters to ADF bounded task flow?

To pass an input parameter to an ADF bounded task flow:

1. Select the input text component on the JSF page.
2. In the Property Inspector, enter a value for the input text component.
3. In the Application Navigator, double-click the name of the called task flow to open its diagram.
4. Click the Overview tab for the called task flow.

What is backing bean scope in ADF?

Backing bean scope: Used for managed beans for page fragments and declarative components only, the object is available from the time an HTTP request is made until a response is sent back to the client.

How do I create a task flow in JDeveloper?

1. In this tutorial, you use Oracle JDeveloper 11.1.
2. Step 1: Create a New Fusion Application and Business Components.
3. Step 2: Create a Bounded Task Flow.
4. Step 3: Build the Task Flow Pages.
5. Step 4: Bind the Task Flow Pages to Data Controls.
6. Step 5: Set the Transaction Control for the Task Flow.
7. Step 6: Define a Second Task Flow.

What is ADF Task Flow?

ADF task flows provide a modular approach for defining control flow in a Fusion web application. Instead of representing an application as a single large JSF page flow, you can break it up into a collection of reusable task flows. Each task flow contains a portion of the application’s navigational graph.

What is ADF scope?

Page flow scope defines a unique storage area for each instance of an ADF bounded task flow. Its lifespan is the ADF bounded task flow, which is longer than request scope and shorter than session scope.

How do I use task flow return in ADF?

Notes:

1. Returning Values to a Calling Task Flow.
2. A task flow return activity causes the ADF bounded task flow to return to the task flow that called it.
3. To return a value, you must specify:
4. Return value definitions on the called bounded task flow.
5. Return values on the task flow call activity in the calling task flow.

What is the difference between bounded and unbounded task flows in ADF?

In ADF Taskflow is of two types. You can secure a Bounded TF, But unbounded TF you can’t. You can pass parameters and get parameters to and from a bounded taskflow, but for Unbounded TF you can’t. Bounded TF has only single entry point, known as default activity, but in unbounded TF multiple entry points are there.

What is bounded task flow in ADF?

A bounded task flow allows reuse, parameters, transaction management, reentry, and can render within an ADF region in a JSF page. For a description of the activity types that you can add to an unbounded or bounded task flow see Chapter 19, “Working with Task Flow Activities”.

How do you run a bounded task flow in ADF?

In the New Gallery, expand Web Tier, select JSF/Facelets and then select ADF Task Flow, and click OK. The dialog shown in Figure 18-9 displays. In the Create Task Flow dialog, the Create as Bounded Task Flow checkbox is selected by default.
