Navigate to another page on value change event of ADF input component

Recently I have seen a thread on OTN forum in that user want to navigate from one page to another on valueChangeListener of input component.

First Method-
This is a simple piece of code to perform navigation to specific page , Use it in ValueChangeListener directly

 FacesContext facesContext = FacesContext.getCurrentInstance();
 facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, "controlFlowName");

Second Method-
ValueChangeListener fires when value of input component changes but it is not meant for navigation, For navigation we use buttons and links with Action property
But for this requirement we have to be a bit tricky, We can queue button Action on value change listener of inputText to navigate to another page
Now first value change listener will be executed and then it'll queue button action to execute and as final outcome user will be able to navigate

Navigating to (open) specific tab in af:panelTabbed programmatically -Oracle ADF

Hello All,
This post is about a development requirement - how to move (navigate or open) to a specific tab in panel tabbed  in Oracle ADF?
Suppose i have to open second tab of af:panelTabbed on a button click, so see how to do this using ADF Faces

• Create a Fusion Web application and a page to drop panel tabbed and a button





• now bind panel tabbed and it's showDetailItem to managed bean, in order to use disclosed property and to get client id
See the code to open (disclose) a specific tab of af:panelTabbed


    //Binding of Panel Tabbed
    private RichPanelTabbed panelTabBind;

    public void setPanelTabBind(RichPanelTabbed panelTabBind) {
        this.panelTabBind = panelTabBind;
    }

    public RichPanelTabbed getPanelTabBind() {
        return panelTabBind;
    }

    /**
     * @Method to disclose (open) specific tab
     * Pass the binding of af:showDetailItem that you want to open
     */
    public void setDisclosedFirstTab(RichShowDetailItem tabBind) {
        RichPanelTabbed richPanelTabbed = getPanelTabBind();
        for (UIComponent child : richPanelTabbed.getChildren()) {
            RichShowDetailItem sdi = (RichShowDetailItem) child;
            if (sdi.getClientId().equals(tabBind.getClientId())) {
                sdi.setDisclosed(true);
            } else {
                sdi.setDisclosed(false);
            }
        }
        AdfFacesContext.getCurrentInstance().addPartialTarget(panelTabBind);
    }



• Now see the code written on button action- here i have checked that which tab is currently disclosed? and based on that i have passed next tab binding to this method





    /**Method to be called on Navigate Button
     * @param actionEvent
     */
    public void naviGateButtonAction(ActionEvent actionEvent) {
        if (firstTabBind.isDisclosed()) {
            setDisclosedFirstTab(secTabBind);
        } else if (secTabBind.isDisclosed()) {
            setDisclosedFirstTab(thirdTabBind);
        } else {
            setDisclosedFirstTab(firstTabBind);
        }
    }



• now run your page and see navigation in af:panelTabbed

Blocking row navigation in af:table , synchronize row selection with model in case of validation failure- Oracle ADF

In ADF we often work on editable af:table and when we use af:table to insert ,update or delete data, it is normal to use some validation
but problem is when some validation failure occurs on page (in af:table) ,still we can select another row and it shows as currently selected Row
this is a bit confusing for user as Row Selection of af:table is not synchronized with model or binding layer

See Problem- 

• I have an editable table on page





• Added a validation to check negative value in field of LocationId, now navigate to another row





• See selected focus is on Academic, but problem is when there is validation failure, why it is showing other row as selected ? 




• If you check in ViewObject , you will find that row with DepartmentName Human Resource is current row

ADF framework provides a property in af:table to control navigation in af:table when there is some error or validation failure- blockRowNavigationOnError
See in oracle docs about this proprty-

Valid Values: always, never, auto


Whether we want to block row navigation in case of validation failure.
This is when you select a row and do some editing inside the table or in a related form, and this editing causes some validation failures. At this time, if you click on a different row in table, we want to block you from moving to the new row.
possible values are: always, never and auto. default value is auto.

• always means we block the row navigation
• never means we don't block and let the row navigation happen
• auto means the framework will make the decision

by default in af:tabel it's value is <auto>

Change it to <always> and now see behavior on page

 now if you try to select another row, it is not get selected and selected focus is on row with validation
