How to create ADF region without Task Flow

Question

I want to divide my page into different regions, but I don't want to have any bounded task flow under each region. I want to include Page Fragment inside the Region.
I find the example of creating Region using some page flow, would you please help me, how to create Region that contains only page fragment, actually the problem I am facing, I don't know what I will provide in value attribute in Region tag, that is expecting some Region Model.

Hello, RajeshBiswas.
A solution could be to generate 'MultiTaskFlow' for indeterminate number of regions or multiple regions on the same page.
It would be necessary to create a single file to define all participating 'TaskFlows' on page:
1. Select 'new -> ADF Task Flow (JSF/Facelets)'
2. May include all 'jsff' files as:
<task-flow-definition id="genericTaskFlow1">
    <default-activity>case1</default-activity>
    <view id="case1">
      <page>/pages/case1.jsff</page>
    </view>
    <use-page-fragments/>
  </task-flow-definition>
  <task-flow-definition id="genericTaskFlow2">
    <default-activity>case2</default-activity>
    <view id="case2">
      <page>/pages/case2.jsff</page>
    </view>
    <use-page-fragments/>
  </task-flow-definition>
It should create a Managed Bean to implement the List of Task Flow Bindings:
1. Create a new Class with de following code:
    private List<TaskFlowBindingAttributes> mTaskFlowBindingAttrs = new ArrayList<TaskFlowBindingAttributes>();
    public MultiRegionBean()
        TaskFlowBindingAttributes tfAttr = new TaskFlowBindingAttributes();
        tfAttr.setId("region1");
        tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/.../ADFTaskFlow.xml", "genericTaskFlow1"));
        mTaskFlowBindingAttrs.add(tfAttr);
        tfAttr = new TaskFlowBindingAttributes();
        tfAttr.setId("region2");
        tfAttr.setTaskFlowId(new TaskFlowId("/WEB-INF/.../ADFTaskFlow.xml", "genericTaskFlow2"));
        mTaskFlowBindingAttrs.add(tfAttr);
    public List<TaskFlowBindingAttributes> getTaskFlowList()
        return mTaskFlowBindingAttrs;
2. Define this new class into the 'adf-config.xml' file as Managed Bean with 'pageFlow' scope.
  <managed-bean id="__1">
    <managed-bean-name>managedBeanName</managed-bean-name>
    <managed-bean-class>className</managed-bean-class>
    <managed-bean-scope>pageFlow</managed-bean-scope>
  </managed-bean>
At the page definition, add a MultiTaskFlow inside <executables> tag:
    <multiTaskFlow id="multiTaskFlow1" taskFlowList="#{pageFlowScope.multiRegionBean.taskFlowList}"
On the page, insert regions in the desired locations. For example:
    <af:group id="g2">
        <af:panelAccordion id="pa1" inlineStyle="width:50%; height:400px;">
                <af:showDetailItem text="showDetailItem 1" id="sdi1">
                <af:region id="r1" value="#{bindings.multiTaskFlow1.taskFlowBindingList[0].regionModel}" >
                </af:region>
                </af:showDetailItem>
        </af:panelAccordion>
        <af:panelAccordion id="pa2" inlineStyle="width:50%;">
                <af:showDetailItem text="showDetailItem 1" id="sdi2">
                <af:region id="r2" value="#{bindings.multiTaskFlow1.taskFlowBindingList[1].regionModel}" >
                </af:region>
                </af:showDetailItem>
        </af:panelAccordion>
    </af:group>
