Using af:deck component to animate content in ADF 12c(12.1.3)

Hello all,
af:deck is new component introduced in ADF 12.1.3, see more detail on Oracle Docs
af:deck-Tag Referance
http://docs.oracle.com/middleware/1213/adf/tag-reference-faces/tagdoc/af_deck.html
ADF Faces Demo Server (deck demo)

As per oracle docs-
The deck component is a container that shows one child component at a time. When changing which child is displayed, the transition can be animated.
This component does not provide any built-in controls for choosing which child is displayed. Instead, you use some other component to control it. For example, you might use an external navigationPane tab bar or perhaps some external commandImageLinks to represent page progress dots. You are not limited to external controls, your deck might be displaying a series of images and you may want to put a link around each image to trigger advancing to the next image. In all of these cases, you will need to use an event handler function to change the displayed child.

So in this post i am going to show - how to use af:deck component with some animation effect?
in this post i am using 6 images to display on 6 different links

• so designed page like this, inside deck there is 6 images, and there are 6 image links outside deck , each link is associated with managed bean actionListener 



<af:panelGroupLayout id="pgl4" layout="horizontal" halign="center">
          <af:link id="l1" icon="#{resource['images:circle-lblue.png']}"
                   actionListener="#{viewScope.DynamicDeckBean.link1Action}" partialSubmit="true"/>
          <af:link id="l2" icon="#{resource['images:circle-lblue.png']}"
                   hoverIcon="#{resource['images:circle-lred.png']}" partialSubmit="true"
                   actionListener="#{viewScope.DynamicDeckBean.link2Action}"/>
          <af:link id="l3" icon="#{resource['images:circle-lblue.png']}"
                   hoverIcon="#{resource['images:circle-lred.png']}" partialSubmit="true"
                   actionListener="#{viewScope.DynamicDeckBean.link3Action}"/>
          <af:link id="l4" icon="#{resource['images:circle-lblue.png']}"
                   hoverIcon="#{resource['images:circle-lred.png']}" partialSubmit="true"
                   actionListener="#{viewScope.DynamicDeckBean.link4Action}"/>
          <af:link id="l5" icon="#{resource['images:circle-lblue.png']}"
                   hoverIcon="#{resource['images:circle-lred.png']}" partialSubmit="true"
                   actionListener="#{viewScope.DynamicDeckBean.link5Action}"/>
          <af:link id="l6" icon="#{resource['images:circle-lblue.png']}"
                   hoverIcon="#{resource['images:circle-lred.png']}" partialSubmit="true"
                   actionListener="#{viewScope.DynamicDeckBean.link6Action}"/>
        </af:panelGroupLayout>

• created binding for deck in managed bean , and added af:transition for back and forward animation for images



<af:deck id="d1" displayedChild="i1" binding="#{viewScope.DynamicDeckBean.deckBind}">
          <af:transition triggerType="forwardNavigate" transition="flipLeft"/>
          <af:transition transition="flipRight" triggerType="backNavigate"/>
          <af:image source="#{resource['images:1.jpg']}" shortDesc="Wild Life 1" id="i1"
                    inlineStyle="height:300px;width:500px;"/>
          <af:image source="#{resource['images:2.jpg']}" shortDesc="Wild Life2" id="i2"
                    inlineStyle="height:300px;width:500px;"/>
          <af:image source="#{resource['images:3.jpg']}" shortDesc="Wild Life3" id="i3"
                    inlineStyle="height:300px;width:500px;"/>
          <af:image source="#{resource['images:4.jpg']}" shortDesc="Wild Life4" id="i4"
                    inlineStyle="height:300px;width:500px;"/>
          <af:image source="#{resource['images:5.jpg']}" shortDesc="Wild Life5" id="i5"
                    inlineStyle="height:300px;width:500px;"/>
          <af:image source="#{resource['images:6.jpg']}" shortDesc="Wild Life6" id="i6"
                    inlineStyle="height:300px;width:500px;"/>
        </af:deck>



• Now page looks like this





• Refer the above links- there is a method to animate deck's child , i have used same method

See managed bean code for links and to animate deck child


    // Animate the display of a deck child.
    private void _animateDeckDisplayedChild(UIComponent eventComponent, int newDisplayedChildIndex) {
        // Find the nearest deck ancestor:
        RichDeck deck = null;
        String eventComponentId = eventComponent.getId();
        while (deck == null) {
            if (eventComponent == null) {
                System.err.println("Unable to locate a deck ancestor from id " + eventComponentId);
                return;
            } else if (eventComponent instanceof RichDeck) {
                deck = (RichDeck) eventComponent;
                break;
            }
            eventComponent = eventComponent.getParent();
        }
        System.out.println("Child is-" + eventComponent.getId());
        String newDisplayedChild = deck.getChildren().get(newDisplayedChildIndex).getId();

        // Update the displayedChild:
        System.out.println("Display Child-" + newDisplayedChild);
        deck.setDisplayedChild(newDisplayedChild);

        // Add this component as a partial target:
        RequestContext.getCurrentInstance().addPartialTarget(deck);
    }


Code to change image and calling method to animate, here 0,1,2 are index no. of deck's children



/**Methods to be called on different links to show different images*/
    public void link1Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 0);// 0 for first child of deck
    }
    public void link2Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 1);// 1 for second child of deck
    }
    public void link3Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 2);
    }
    public void link4Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 3);
    }
    public void link5Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 4);
    }
    public void link6Action(ActionEvent actionEvent) {
        UIComponent eventComponent = deckBind;
        _animateDeckDisplayedChild(eventComponent, 5);
    }



• Now run application and click on links :) see how deck works
