fragment如何主动传值给父页面，父页面被动接收做逻辑，像Listener一样

#2

看看这个：Jmix 还有全局事件这个功能么 - Jmix - jmix.cn

看了英文论坛，使用这种方法实现了

Fragment

public Subscription addChangeListener(Consumer<FragmentChangeEvent> listener) {
        return getEventHub().subscribe(FragmentChangeEvent.class, listener);
    }

    public static class FragmentChangeEvent extends EventObject {

        private BusinessHoursDTO businessHoursDTO;

        /**
         * Constructs a prototypical Event.
         *
         * @param source the object on which the Event initially occurred
         * @throws IllegalArgumentException if source is null
         */
        public FragmentChangeEvent(Object source, BusinessHoursDTO businessHoursDTO) {
            super(source);
            this.businessHoursDTO = businessHoursDTO;
        }

        public BusinessHoursDTO getBusinessHoursDTO() {
            return businessHoursDTO;
        }
    }


    @Subscribe("businessHour")
    public void onBusinessHourValueChange(final HasValue.ValueChangeEvent event) {
        fireEvent(FragmentChangeEvent.class, new FragmentChangeEvent(this, businessHoursDTO));
    }

父页面

@Subscribe(id = "businesshoursFragment", target = Target.CONTROLLER)
    protected void onBusinessHourValueChange(BusinessHoursFragment.FragmentChangeEvent event) {
        // 营业时间组件值变更
//        getEditedEntity().setFdBussinessTimeType();
        BusinessHoursDTO businessHoursDTO = event.getBusinessHoursDTO();
        getEditedEntity().setFdBusinesshours(businessHoursDTO.getBusinessTimeType().getId());
        getEditedEntity().setFdBusinesshours(businessHoursDTO.getValue());
    }

您这个全局事件功能，我后面学习下。

这样写之后发现，hotdeploy无效了。
每次都要重启才行，大佬帮看一下是不是个BUG？
