ADF Task Flow Return Activity

Return Activity is used when bounded task flow completes and send control flow back to caller.Return activity works only with the bounded task flow.Return task flow's reentry is option is set only if the task flow's reentry-outcome-dependent is set.End transaction option is available for the Return activity for transaction commit and rollback.Also we can set the restore save point option to either true or false.

Create a called task flow as below

return_called_view1.jsff

<?xml version='1.0' encoding='UTF-8'?>

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">

  <af:panelGroupLayout id="pgl1">

    <af:outputText value="Return Activity Calling TF" id="ot1"/>

    <af:button text="button 1" id="b1" action="testOutCome"/>

  </af:panelGroupLayout>

</jsp:root>

return_called_view1.jsff :

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">

  <af:panelGroupLayout id="pgl1">

    <af:outputText value="Called Task Flow" id="ot1"/>

    <af:button text="Calling Retun" id="b1" action="toReturn"/>

  </af:panelGroupLayout>

</jsp:root>

Task flow return activity options are as shown below 

The outcome "goToView2" is the control flow case defined in the calling task flow. Also look at the other options like Reentry,End Transaction and Restore Save Point.

Calling Task flow:

Also set the listeners for the task flow call activity. Below the managed bean for the before and after listener for the task flow call activity.

package test.view;

public class TFCallActivityListeners {

    public TFCallActivityListeners() {

        super();

    }

    public void beforeListerner() {

        System.out.println("Before listener called ");

    }

    public void afterListener() {

        System.out.println("After listener called ");

    }

}

The code for the jspx files in the calling task flow

return_view1.jspx 

<?xml version='1.0' encoding='UTF-8'?>

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">

  <af:panelGroupLayout id="pgl1">

    <af:outputText value="Return activity" id="ot1"/>

    <af:button text="button 1" id="b1" action="tocall"/>

  </af:panelGroupLayout>

</jsp:root>

return_view2.jspx 

<?xml version='1.0' encoding='UTF-8'?>

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:af="http://xmlns.oracle.com/adf/faces/rich">

  <af:panelGroupLayout id="pgl1">

    <af:outputText value="To view2" id="ot1"/>

  </af:panelGroupLayout>

</jsp:root>

Drag and drop the calling task flow to a jspx file as a region and run the page. Click through the command buttons to reach the final view in the UI.Check the jdeveloper log to see the after listeners are executed.
