无线电中的Wicket本地模型

Question

我用无线电解决了一个问题，换了一个新的。我有自己的客户radioGroup组件：

public class OperationDateRadioGroup extends RadioGroup<OperationDate> {

    private LocalDatePicker date;
    private LocalDatePicker from;
    private LocalDatePicker to;
    public OperationDateRadioGroup(String id, IModel<OperationDate> model) {
        super(id, model);
    }

    @Override
    protected void onInitialize() {
        super.onInitialize();
        operationDateType = getModelObject().getOperationDateType();

        date = new LocalDatePicker("date", new CompoundPropertyModel<>(getModel()).bind("date")) {

            @Override
            protected void onConfigure() {
                super.onConfigure();
                setEnabled(OperationDateRadioGroup.this.getModelObject().getOperationDateType() == OperationDateType.DATE);
            }
        };
        from = new LocalDatePicker("interval.from", new CompoundPropertyModel<>(getModel()).bind("interval.from")) {

            @Override
            protected void onConfigure() {
                super.onConfigure();
                setEnabled(OperationDateRadioGroup.this.getModelObject().getOperationDateType() == OperationDateType.INTERVAL);
            }
        };
        to = new LocalDatePicker("interval.to", new CompoundPropertyModel<>(getModel()).bind("interval.to")) {

            @Override
            protected void onConfigure() {
                super.onConfigure();
                setEnabled(OperationDateRadioGroup.this.getModelObject().getOperationDateType() == OperationDateType.INTERVAL);
            }
        };

        OperationDate operationDate = new OperationDate();
        operationDate.setOperationDateType(OperationDateType.DATE);
        Radio dateType = new Radio<>("dateType", Model.of(operationDate));
        OperationDate operationInterval = new OperationDate();
        operationInterval.setOperationDateType(OperationDateType.INTERVAL);
        Radio intervalType = new Radio<>("intervalType", Model.of(operationInterval));

        dateType.add(new AjaxFormSubmitBehavior("onchange") {
            private static final long serialVersionUID = -6001312248222404593L;

            @Override
            protected void onEvent(AjaxRequestTarget ajaxRequestTarget) {
                ajaxRequestTarget.add(date, from, to);
            }
        });

        intervalType.add(new AjaxEventBehavior("onchange") {
            private static final long serialVersionUID = -6001312248222404593L;

            @Override
            protected void onEvent(AjaxRequestTarget ajaxRequestTarget) {
                ajaxRequestTarget.add(date, from, to);
            }
        });

        add(dateType, intervalType);
        add(date.setOutputMarkupId(true));
        add(from.setOutputMarkupId(true));
        add(to.setOutputMarkupId(true));
        add(new AjaxFormChoiceComponentUpdatingBehavior() {
            @Override
            protected void onUpdate(AjaxRequestTarget ajaxRequestTarget) {

            }
        });
        getForm().add(new DateIntervalFormValidator(this, date, from, to));
    }
}

我把radioGroup放在FormComponentPanel的地方

public class OperationDatePanel extends FormComponentPanel<OperationDate> {
 ....
    @Override
    protected void onInitialize() {
        super.onInitialize();
        add(new OperationDateRadioGroup("operationDate", getModel()));
    }
}

问题:当我在页面更改内部( radioGroup )组件和外部( radioGroup )模型中选择radio时，我只需要更改radioGroup模型，而通过提交更改外部模型。

Answer 1

我认为，这个问题是因为您将outer(Page)模型传递到OperationDateRadioGroup构造函数中

add(new OperationDateRadioGroup("operationDate", /*Here you are passing PAGE model*/ getModel()));

它可以和这个page model一起工作。您需要将任何其他模型传递给构造函数并使用此模型。
