Using Multiple Selection (selectManyListbox & selectManyCheckbox component) in ADF

Hello All ,
This tutorial is based on use of selectManyListbox & selectManyCheckbox component in ADF to enable multiple selection.
Both component are same in functionality only somewhat different in look-feel.

Follow steps to use these component -



  • Create a fusion web application and create business components for Departments table of HR Schema

  • Now create a page and drop Departments Vo from data control on page as multiple selection (checkbox or listbox) 




  • Now binding for this component is created in page-bindings, add a button on page to get total selected values


  • See how to get selected values in managed bean, JUCtrlListBinding is used to get selected values

    • import javax.faces.event.ActionEvent;

import oracle.adf.model.BindingContext;

import oracle.binding.BindingContainer;

import oracle.jbo.uicli.binding.JUCtrlListBinding;   

 public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    public void getSelectedValue(ActionEvent actionEvent) {

        JUCtrlListBinding listBindings = (JUCtrlListBinding)getBindings().get("DepartmentsView1");
        Object str[] = listBindings.getSelectedValues();
        for (int i = 0; i < str.length; i++) {
            System.out.println(str[i]);
        }
    }

  • this method works for both listbox and checkbox, i have added all selected departments in a FacesMessage and displayed on page

 Select All-
 


And Check-box component look like this-


Complete code written on 'Get Selected Values' button-


    /**Method to get BindingContainer of page
     * @return
     */
    public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    /**Method to get Selected Values
     * @param actionEvent
     */
    public void getSelectedValue(ActionEvent actionEvent) {

        JUCtrlListBinding listBindings = (JUCtrlListBinding)getBindings().get("DepartmentsView1");
        Object str[] = listBindings.getSelectedValues();
        StringBuilder saveMsg =
            new StringBuilder("<html><body><b><p style='color:red'>Selected Departments are-</p></b>");

        saveMsg.append("<ul>");
        for (int i = 0; i < str.length; i++) {
            System.out.println(str[i]);
            saveMsg.append("<li> <b>" + str[i].toString() + "</b></li>");
        }

        saveMsg.append("</ul><br>");
        saveMsg.append("</body></html>");
        FacesMessage msg = new FacesMessage(saveMsg.toString());
        FacesContext.getCurrentInstance().addMessage(null, msg);

    }

      Have you checked sample application ?
      and this error is due to wrong type , once check your import statements

    i checked your sample app. You are also using string type for base attribute.

    could you please help me how to overcome this exception.

    Hi Ashish,


    If i change the base attribute to int type attribute then it works but in my managed bean i get the selected values as 1,2 etc like this but i want the original values.

    In your sample app you are using the base attribute as string type attribute (DepartName) but there is no error don't what i am doing wrong.

      Yes you need to use integer value as base attribute , In some Jdev version string is not accepted
      Which Jdev version you are using ?
      Alternate way is to use filter viewObject with departmentId and get Department Name
      Like this

      deptVo.getFilteredRows("DepartmentId",value);
