Navigating from calendar activity by clicking in Oracle ADF – Techartifact

af:calendar component in ADF is widely used.It is same as Google calendar we used. In calendar we are having different activities .We are having different calendar facet inside the calendar component i. e activitydetail, activityDelete, activityHover, activityContextMenu, create , contextMenu.

If you look down the property of calendar component inside property pallet. you will not find action or actionListener property instead of you will get
calendarActivity, calendarListener etc.

Now my requirment is to clicking on the calendar component , it should navigate to diffrent page in same taskflow. How to do that.Little tricky
According to calendar component we can have this navigation easily by the child component or from the calendar facet. We can have a show a popup
in the activityHover facet. In the popup window we can have the button ,inside the button action property we can define the control flow case or some string which we defined in the taskflow diagram for navigation. If you do like this when you hover over the calendar activity a pop up window will come and you will get button with some other detail , when you click the button you will be navigated to new page. look easy…….

But my requirment is navigate after clicking the acitivity . Then i made that button visible property to false .I created a managed bean and inside the activityListener of calendar component i wrote a method and invoke the button action programmatic and queue the action event as i described in my old post

 
        UIComponent component = null;
        FacesContext facesContext = FacesContext.getCurrentInstance();
        if (facesContext != null) {
          UIComponent root = facesContext.getViewRoot();
          component = findComponent(root, "buttonId");
        }
        
        
        // UIViewRoot root = facesContext.getViewRoot();
        //cb1 is the fully qualified name of the button
        RichCommandButton button = (RichCommandButton)component;
        ActionEvent actionEvent = new ActionEvent(button);
        actionEvent.queue();

Queue an action event or invoking the button action in programmatic way in JSF /ADF – Techartifact

Sometimes our requirement is to invoke the button’s action in programmatic way without needing a user to click a button,. For example we want navigation happening automatically without clicking the button by user i.e implementing navigation in programmatic way using Java.We can queue an action event . In this case the developer may drag and drop a button in the page and binds its action property to some static action outcome or to a method that returns a String, and set Visible property for the button to false. At some point the developer can invoke this button’s action by using this code.

 

FacesContext facesContext = FacesContext.getCurrentInstance();
UIViewRoot root = facesContext.getViewRoot();   
//cb1 is the fully qualified name of the button
RichCommandButton button = (RichCommandButton) root.findComponent(“cb1″); // cb1 will be id of invisible button
ActionEvent actionEvent = new ActionEvent(button);
actionEvent.queue();        // we are queuing the all action programmaticly

an another code snippet which will work in this scenario

 

        UIComponent component = null;
        FacesContext facesContext = FacesContext.getCurrentInstance();
        if (facesContext != null) {
          UIComponent root = facesContext.getViewRoot();
          component = findComponent(root, "button_id");  // button_id will be id of invisible button
        }
        
        RichCommandButton button = (RichCommandButton)component;
        ActionEvent actionEvent = new ActionEvent(button);
        actionEvent.queue();   // we are queuing the all action programmaticly

getting Attribute value from View Object column in ADF

Hi All,

When ever we want to have value of some attribute we can use below code .It work fine in managed and backing bean .
Create a java class and import 

 
import oracle.adf.model.BindingContext;
import oracle.adf.model.binding.DCBindingContainer;

import oracle.adf.model.binding.DCIteratorBinding;

and using below code get value of any attribute

 
        BindingContext ctx = BindingContext.getCurrent();
        DCBindingContainer bc = (DCBindingContainer)ctx.getCurrentBindingsEntry();
        DCIteratorBinding iterator = bc.findIteratorBinding("ViewObjectIterator");
        Row r = iterator.getCurrentRow();
        String empNameValue = (String)r.getAttribute("EmpName");
