ADF Page to render Unknown Number of Regions

Create two task flows

Task Flow 1:

dyregion_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="Region 1" id="ot1"/>

  </af:panelGroupLayout>

</jsp:root>

Task Flow 2:

dynamicRegion_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="Region 2" id="ot1"/>

  </af:panelGroupLayout>

</jsp:root>

Create the managed bean in the pageFlowScope. The code for the managed bean is as below

package view;

import java.util.ArrayList;

import java.util.List;

import oracle.adf.controller.TaskFlowId;

import oracle.adf.controller.binding.TaskFlowBindingAttributes;

public class MultiBean {

  

   private List<TaskFlowBindingAttributes> mattrs= new ArrayList<TaskFlowBindingAttributes>(5);

   public MultiBean() {

      

       TaskFlowBindingAttributes tfAttr= new TaskFlowBindingAttributes();

       tfAttr.setId("region1");

       tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/tfDynamicRegion.xml","tfDynamicRegion"));

       mattrs.add(tfAttr);

      

       tfAttr= new TaskFlowBindingAttributes();

       tfAttr.setId("region2");

       tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/tfDyanamicRegion1.xml","tfDyanamicRegion1"));

       mattrs.add(tfAttr);

   }

   public List<TaskFlowBindingAttributes> getTaskFlowList() {

       return mattrs;

   }

  

}
