我在List界面中添加了一个按钮,点击按钮的时候,会给选中的这条数据进行一些操作,但运行到这条数据的实体的Set方法时,会出现:Cannot invoke com.vaadin.flow.component.Component.getElement()" because "recreatedComponent" is null
,目前只在后台任务中写了set方法会出现问题,其他情况暂未发生。
相关代码能发一下吗?
我修改了代码了,等下次遇到这个问题的时候我再贴一下,麻烦您了
我现在遇到的是调用set方法的时候出现上面这个异常,我现在是在List页面点击一个按钮,给这条数据的版本状态设置为“生效”,在set的时候出现问题,但并没有使用后台任务。下面是我的代码:
@Subscribe("invoiceBasicInfoesDataGrid.effective")
public void onInvoiceBasicInfoesDataGridEffective(final ActionPerformedEvent event) {
InvoiceBasicInfo invoiceBasicInfo = invoiceBasicInfoesDataGrid.getSingleSelectedItem();
invoiceBasicInfo.setVersionStatus("生效");
dataManager.save(invoiceBasicInfo);
invoiceBasicInfoesDl.load();
}
下面是错误堆栈

我在 2.3.3 试了,没重现,你的Jmix版本是?
目前是组件化开发的,组件2.3.0,项目是2.3.1,那我全升级到2.3.3再试试
