    Default text field on radio listener help

    text field on radio listener help


    Hi! I am trying to add a text field upon clicking a radio button but it doesn't seem to work. What I want to do is display different text fields depending on the radio button clicked. It prints the message "done" but it won't load/add the textfield. Am I missing some code? What do I need to add to this to make it work? What is rendering, is it what I need to do? Thank you.


    Code:
    public class Upload {
    
        Widget page = new Widget();
        final FormPanel mainPanel = new FormPanel();
        
        public Uploasd(String wholeName, final int user_id, final int schId) {
            mainPanel.setHeading("Upload Work");
            mainPanel.setEncoding(Encoding.MULTIPART);
            mainPanel.setMethod(Method.POST);
            mainPanel.setWidth(775);
            FormLayout fLayout1 = new FormLayout();
            fLayout1.setLabelWidth(110);
            fLayout1.setPadding(5);
            mainPanel.setLayout(fLayout1);
            
            FileUploadField file = new FileUploadField();  
            file.setAllowBlank(false);  
            file.setFieldLabel("File");
            mainPanel.add(file);
            
            RadioGroup license = new RadioGroup("privacy");  
            license.setFieldLabel("Privacy");  
            license.add(radio);  
            license.add(radio2);  
            license.add(radio3);
            mainPanel.add(license); 
            
            final Radio tList = new Radio();
            tList.setWidth(120);
            tList.setName("assess");
            tList.setId("2");
            tList.setBoxLabel("from list");
            tList.setToolTip("choose from the complete list of evaluators in the system");
            tList.setValue(true);  
            
            final Radio rubric = new Radio();  
            rubric.setName("assess"); 
            rubric.setId("1");
            rubric.setItemId("1");
            rubric.setWidth(120);
            rubric.setToolTip("choose from teachers with the specified rubric keyword");
            rubric.setBoxLabel("with rubric...");
            rubric.setValue(false);
            
            RadioGroup assessors = new RadioGroup("evaluators");  
            assessors.setFieldLabel("Evaluators");  
            assessors.add(tList);  
            assessors.add(rubric);  
            mainPanel.add(assessors);
                    
            final TextField testing1 = new TextField();
            testing1.setFieldLabel("Teacher's Name");
            testing1.setBorders(true);
            final HorizontalPanel testPanel1 = new HorizontalPanel();
            testPanel.add(testing1);
            
            final TextField testing2 = new TextField();
            testing2.setFieldLabel("Teacher's Name");
            testing2.setBorders(true);
            final HorizontalPanel testPanel2 = new HorizontalPanel();
            testPanel.add(testing2);
    
            tList.addListener(Events.OnClick, new Listener<FieldEvent>() {
                public void handleEvent(FieldEvent be) {                
                    if (be.field.getId() == "2") {
                        mainPanel.add(testPanel);
                        System.out.println("done1");
    
                    }        
                }
            });
            
             rubric.addListener(Events.OnClick, new Listener<FieldEvent>() {
                public void handleEvent(FieldEvent be) {                
                    if (be.field.getId() == "1") {
                        mainPanel.add(testPanel2);
                        System.out.println("done2");
    
                    }        
                }
            });
            page = mainPanel;
        }
        public Widget getWidget() {
            return page;
        }
        
    }
