Shuttle Component in Oracle ADF (Allow Multiple Selection), Get Selected values from Shuttle Component

Shuttle Component in Oracle ADF
Shuttle component supports multiple selection at Runtime, when we need to select multiple records at runtime then we can use Shuttle Component.
Now we see how to use shuttle component (af:selectManyShuttle) in Oracle ADF
Follow these steps-

  • Prepare model for Employees table of HR Schema(Create EO,VO and AM)
  • Now drag Employees ViewObject from DataControl to page and select multiple selection-->ADF Select Many Shuttle-
Drop ViewObject as ADF Select Many Shuttle






  • Now edit binding for this Shuttle Component,choose attribute that you want to show and also base attribute-
    Edit Shuttle binding and select base and display attribute

     
  • Now it will look like this, drag a button to get selected attribute of this shuttle component
    af:selectManyShuttle
     
    Now write code on button's actionEvent to get selected value from Shuttle-


    import oracle.adf.model.BindingContext;
    import oracle.binding.BindingContainer;
    
        /*****Generic Method to get BindingContainer of current page, fragment or region**/
        public BindingContainer getBindingsCont() {
            return BindingContext.getCurrent().getCurrentBindingsEntry();
        }
    

     public void getSelectedValue(ActionEvent actionEvent) {
          //Get Binding Continer of Page
            BindingContainer bc = this.getBindings();
         //Get shuttle binding from pagedef
            JUCtrlListBinding listBindings = (JUCtrlListBinding)bc.get("Employees1");
        //Get Selected Values
            Object str[] = listBindings.getSelectedValues();
        //Iterate over selected values
            for (int i = 0; i < str.length; i++) {
                System.out.println(str[i]);
            }
        }
    

    When you run this it should look like this and your Shuttle is ready
    Get selected value of shuttle component ADF
