                AjaxEditableLabel taskTypeEditableLabel = new AjaxEditableLabel("taskTypeEditableLabel", new Model(value)) {

                    private static final long serialVersionUID = 10061L;

                    @Override
                    public void onSubmit(AjaxRequestTarget target) {
                        super.onSubmit(target);
                        String input = (String) getModelObject();
                        if (input != null) {                                
                            taskTypeSettingsFormModel.getTaskTypeList().set(index, input);                              
                        }                                                   
                    }       

                    @Override
                    protected FormComponent newEditor(MarkupContainer parent, String componentId, IModel model) {
                        FormComponent editor = super.newEditor(parent, componentId, model);

                        editor.add(new AbstractBehavior() {

                            public void beforeRender(final Component component) {
                                super.beforeRender(component);
