Traverse POJO based ADF treeTable, Get Child nodes of selected parent

Previosuly I have posted about populating af:treeTable programmatically and getting selected records from POJO based treeTable

This post is next in that series and here I am extending same sample application that show a tree of Seasons and it's characters
First we will see How to traverse a POJO based treeTable (Iterate through all nodes of treeTable)

Basic idea is to get treeTable Collection Model and iterate over it to get all nodes value, To get CollectionModel created treeTable component binding in managed bean

Get Selected records (Child/Parent) from POJO based ADF treeTable

Hello All
Previously I have posted about creating af:treeTable programmatically using POJO and this the next post in series

In this post I am talking about a very common requirement while using POJO based treeTable
How can we get selected records (child/parent) from POJO based treeTable ?

For this post I am extending same sample application, Till now we have seen that how can we create POJO based treeTable
Now we'll see that how to get it's selected records

Populate af:treeTable programatically using POJO in Oracle ADF (11g & 12c)

Hello All
This post is about creating & populating af:treeTable programmatically in ADF 11g and 12c
treeTable is basically a hierarchical representation of data, using ADF model layer we can create treeTable very easily by defining master-detail relation between viewObjects
see my previous posts on treeTable-
Tree Table Component in Oracle ADF(Hierarchical Representation)
Tree Table Component with declarative presentation in ADF, Access childs without custom selection listener
Expand and Collapse an af:treeTable programmatically in ADF Faces (Oracle ADF)
Refreshing Child Nodes of an af:treeTable / af:tree in Oracle ADF

to populate treeTable programmatically we need to configure data set that fits to tree hierarchy
thanks to Chris Muir's post about programmatic creation of treeTable

there is 4-5 simple steps to do-
  • Create a fusion web application and drop a af:treeTable on page , in treeTable creation wizard select "bind later" 

  • now create managed bean to populate data in treeTable, create a simple List in managed bean of type POJO class (a java class that contains attributes and their accessor  )
  • so in this app i am going to Tv Serial and respective character names in treeTable, for that i have created a class that contains POJO for treeTable

  • import java.util.ArrayList;
    import java.util.List;
    public class Seasons {
        public Seasons(String name) {
   = name; // To Store Header Values (Storing Seasons Name :))
            characters = new ArrayList<Seasons>(); // To Store Detail Values (Storing Season's Charatcers)
        public void setCharacters(List<Seasons> empDet) {
            this.characters = empDet;
        public List<Seasons> getCharacters() {
            return characters;
        private String name;
        private List<Seasons> characters;
        public void setName(String name) {
   = name;
        public String getName() {
            return name;
    // This methods directly add characters value in list
        public void addEmp(Seasons employee) {

  • In this class the characters list behaves as child of seasons, so in managed bean define a top-level list (that contains both master and detail) and add values

  • See managed Bean Code-
    import java.util.ArrayList;
    import java.util.List;
    import org.apache.myfaces.trinidad.model.ChildPropertyTreeModel;
    public class ProgrammaticTreeTabBean {
        List<Seasons> seasonList = new ArrayList<Seasons>();
        ChildPropertyTreeModel charatcerVal;
        public ProgrammaticTreeTabBean() {
            // Creating tree for Seasons and Characters details
            // Adding Master Values (seasons)
            Seasons season1 = new Seasons("Game of Thrones");
           // Adding Detail Values (Child Node-Characters)
            Seasons character = new Seasons("Tywin Lannister");
            character = new Seasons("Tyrion Lannister");
            character = new Seasons("Jaime Lannister");
            character = new Seasons("Cersie Lannister");
            character = new Seasons("Ned Stark");
            // Adding Master Values (seasons)
            Seasons season2 = new Seasons("Arrow");
            // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Oliver Queen");
            character = new Seasons("Moira Queen");
            character = new Seasons("Laurel Lance");
            character = new Seasons("Sara Lance");
            // Adding Master Values (seasons)
            Seasons season3 = new Seasons("Vikings");
          // Adding Detail Values (Child Node-Characters)
            character = new Seasons("Ragnar Lothrak");
            // Adding all list to topList
            // Filtering Child Data, ChildPropertyTreeModel creates a TreeModel from a List of beans, see
            charatcerVal = new ChildPropertyTreeModel(seasonList, "characters");
        public ChildPropertyTreeModel getCharatcerVal() {
            return charatcerVal;

  • Now code part is complete, now configure your treeTable to show data, see XML source of af:treeTable

  • <af:treeTable rowBandingInterval="0" id="tt1"
                                  value="#{pageFlowScope.ProgrammaticTreeTabBean.charatcerVal}" var="node"
                                  rowSelection="single" initiallyExpanded="true">
                        <f:facet name="nodeStamp">
                            <af:column headerText="Node Stamp" id="c1" width="250">
                                <af:outputText value="#{}" id="ot1" inlineStyle="font-weight:bold;"/>

  • Now run your application and check , what you have done ;)
Happy Learning :) Sample ADF Application (12.1.3)
