Access nested h:dataTable programatically in Java

Question

Hi everyone. I've got an h:dataTable which is nested three levels deep, but also within some other components. Does anyone have a good solution to get a handle on the rowData() of the internally nested tables? Do I need to recursively traverse all of the children searching for a table? It's hard to use UIComponent.findComponent("") because the table ID is dynamically generated... etc.
The first level table is bound to a backing bean where I am attempting to get these references.
Thoughts? Thanks!

Anyway, I did a quick create and test and it just worked..
MyBeanpublic class MyBean {
    private HtmlDataTable parent;
    private HtmlDataTable child;
    private List<MyData> list;
    public MyBean() {
        list = new ArrayList<MyData>();
        list.add(new MyData("parent1", "nested1a", "nested1b", "nested1c"));
        list.add(new MyData("parent2", "nested2a", "nested2b", "nested2c"));
        list.add(new MyData("parent3", "nested3a", "nested3b", "nested3c"));
    public void submit() {
        System.out.println(child.getRowData());
    public HtmlDataTable getParent() {
        return parent;
    public HtmlDataTable getChild() {
        return child;
    public List<MyData> getList() {
        return list;
    public void setParent(HtmlDataTable parent) {
        this.parent = parent;
    public void setChild(HtmlDataTable child) {
        this.child = child;
    public void setList(List<MyData> list) {
        this.list = list;
}MyDatapublic class MyData {
    private String value;
    private List<MyData> list;
    public MyData() {
    public MyData(String value) {
        this.value = value;
    public MyData(String value, String... nestedValues) {
        this(value);
        this.list = new ArrayList<MyData>();
        for (String nestedValue : nestedValues) {
            this.list.add(new MyData(nestedValue));
    public String getValue() {
        return value;
    public List<MyData> getList() {
        return list;
    public void setValue(String value) {
        this.value = value;
    public void setList(List<MyData> list) {
        this.list = list;
    public String toString() {
        return value;
