ADF 11g R2 : Using the ActiveRowKey property

In ADF 11g Release 2, the ADF Table component has a property called ‘ActiveRowKey’. According to documentation, this represents the row that is currently active on the client. In click-to-edit mode, the active row will be made editable and is brought into view (if not already visible). Upon initial display, the click-to-edit component defaults the active row to the first visible row. In this post I will show you how to use the activeRowKey programmatic

Use Case.

Imagine the following use case: I have a ‘click-to-edit’ table and I added a ‘filter’ field with a button in the surrounding panel collection. User enters (in this case) a last name and pushes the button. The table scrolls to the first row that matches the criteria, and the row is active to edit.


I create an ADF table based on ADF business components for the Employees table.
It’s a clickToEdit table with singleSelection. After creating it I bind it to a bean. I’ll show later why I need to do that. The table code looks like this:

             <af:table value="#{bindings.Employees1.collectionModel}" var="row"
                      emptyText="#{bindings.Employees1.viewable ? 'No data to display.' : 'Access Denied.'}"
                      rowSelection="single" id="t1" editingMode="clickToEdit"
              <af:column ....................

Next I surround it with a panel collection and I turn off a lot of features (also new in R2) of the panel collection. In the toolbar facet I add an inputText component and a commanfbutton. The inputtext will hold the search value, and the button invokes logic to scroll the table and make to row active.

           <af:panelCollection id="pc1" featuresOff="viewMenu detach" >
            <f:facet name="menus"/>
            <f:facet name="toolbar">
            <af:toolbar id="t2">
            <af:group id="g1">
            <af:inputText label="enter last name" value="#{pageFlowScope.empsBean.searchValue}" id="it11"/>
            <af:commandToolbarButton  text="goto employee" id="ctb1"

In the actionListener I first get a hold of the RowSetItetator. For each and every row in the rowSetIterator, I check if it matches the entered search string. I do that in a separate method called matchFound() (see line 8).

   public void gotoPressed(ActionEvent actionEvent) {
    // Add event code here...
    DCIteratorBinding it = ADFUtils.findIterator("Employees1Iterator");
    RowSetIterator rsi = it.getRowSetIterator();
    RowKeySet oldSelection = empTable.getSelectedRowKeys();

    if (rsi.first() != null) {
      Row r = rsi.first();
           while (rsi.hasNext() && getKey() == null && (!matchFound(r,oldSelection))) {
                   r =;

In the matchFound() method I compare the value of the LastName attribute with the value entered by the user (see line 7). If it is a match there are two more things I need to do. First I add the key of the row found to be the activeRowKey (see line 11). Finally I need to make the row current. If I don’t do this, it will still work, but by making the row current, it just looks a lot nicer. The trick I use here (see line 13) is a method (line 19) that I borrowed from Frank Nimphius’ blog.

   private boolean matchFound (Row r,RowKeySet oldSelection){
    ArrayList lst = new ArrayList(1);
    RowKeySetImpl newSelection = new RowKeySetImpl();
    Key key = null;
    String rowValue = (String)r.getAttribute("LastName");
    if (rowValue.toString().contains(searchValue)) {
      System.out.println("now setting key to " + key);
      key = r.getKey();
      makeCurrent(empTable, newSelection, oldSelection);
      return true;
    return false;

  private void makeCurrent(RichTable empTable, RowKeySet newCurrentRow, RowKeySet oldCurrentRow) {
    //To make a row current, we need to create a SelectionEvent which
    //expects the following arguments: component, unselected_keys,
    //selected_keys. In our example, we don't have unselected keys and
    //therefore create an empty RowSet for this
    SelectionEvent selectionEvent =
      new SelectionEvent(oldCurrentRow, newCurrentRow, empTable);

The works.

Start the application, type some searchText, push the button and of you go.
The row is found, and immediate available for edit.
