Dynamically add region at runtime

1-      Create a .jspx page based on your template as usual  and leave it blank until this time

2-      Create  all the bounded taskflows  that you wants and create the page fragments as usual.

3-      Create a java bean class called"DhamanJavaBean"

Package org.dhaman

import oracle.adf.controller.TaskFlowId;

public class DhamanJavaBean {

    private String taskFlowId = "/WEB-INF/emp-flow.xml#emp-flow";

    public DhamanJavaBean () {

        super();

    }

     public TaskFlowId getDynamicTaskFlowId() {

      return TaskFlowId.parse(taskFlowId);

  }

} 

At this moment the calss contains only one attribute " taskFlowId" and only one method " getDynamicTaskFlowId()"

1-      Double click the "adfc-conf.xml" unbound taskflow and click on overview tab to add a new managed ben as follow:

-          Name:          dhamaBean

-          Class :          org.dhaman .DhamanJavaBean

-          Scope:          pageflow

2-      Now return to the  ".jspx" page and click on "Bindins" tab at the button of the page to open the  page definition bindings page.

3-      Under executable click add and select "adf task flow bindings" and select "task flow"

1-      Click ok  - the dialog will appear

1-      Id: region   " or you can write any name you like"

2-      taskFlowId: #{pageFlowScope.dhamanBean.dynamicTaskFlowId}   " this is the the method in the managed bean that will return the taskflow Id"

3-      click ok and return to the source of the page " I mean the jsf source"

4-      add a region tag under the facetRef  like this

         

                     value="#{bindings.region.regionModel}"/>

          >

1-      save all

2-      go to DataBindings.cpx and click on it and go to the structure window

  

1-      you will  add a "definition factory" in the databindings structure by right click on the Databindings and select "insert inside databinding" and select definition factory.

2-      A new folder will be created as "definitionFactories"

3-      Right click on that folder and select "insert inside" and select factory

-          Namespace:    http://xmlns.oracle.com/adf/controller/binding

-          className:   oracle.adf.controller.internal.binding.TaskFlowBindingDefFactoryImpl

1-      save all

1-      for testing add a default value for the " taskFlowId" in the java class. The default value is the task flow file  name followed by "#" and taskflow id as show in the example

2-      now run the .jspx file
