java - 将 DatePicker 转换为 java.util.Date
我在 Vaadin 11 中有一个 DatePicker,我正在尝试绑定到 Date 字段。看起来像这样的东西会起作用:
但我收到以下错误:
如果需要,这里是 MatchEntry 类:
vaadin - Vaadin 11: refreshAll (again)
here is a good thread about DataProvider.refreshAll() on Vaadin 8.5.1, but it doesn't seem to work this way in Vaadin 11.
I used this starter app to play around. It displays some imaginary product data in a grid.
At first, I added a refresh command to SampleCrudView:
The folks from vaadin override getId() in their ProductDataProvider like this to use it as an object identifier:
That ProductDataProvider extends ListDataProvider, which is initialized on startup with data from MockDataService, so that we always deal with the same objects. I changed that:
So now you will get new Product instances within the same ID range every time you call getAllProducts():
So the point is, this doesn't work - the data in the grid is still the same after "refresh" has been clicked.
Any suggestions?

charts - Vaadin 13 饼图没有用我的数据 DataSeriesItem(“Mercury”,4900))替换演示数据(网络浏览器);
我不想在饼图中有演示数据(网络浏览器)。我想覆盖这个。但它不在乎。它不显示任何错误,但始终只显示 Web 浏览器数据。不是我的:“水星”、4900 “金星”、12100
