Vaadin 8 Grid的奇怪错误
我有一个奇怪的浮动虫，Vaadin网格不时出现。第一件事是网格有行重复，前提是数据不重复。第二个是当我点击dublicated行click事件可能包含相应行或相邻行的值。行似乎相互重叠。
解释
在上图（图№1）中，我们可以看到网格。我们考虑三行：AHTO-18，AHTO-22，AHTO-29（第一列的值）。如果我点击第一个AHTO-18预期的行为是窗口，应该打开AHTO-18的详细信息。但是打开的窗口包含另一行的详细信息（AHELAID而不是AHTO-18）。它可以在下面的图片中看到（图№2）。
然后我向下滚动网格，第二次找到这三行（AHTO-18，AHTO-22，AHTO-29）。如下图所示（图№3）。
如果点击AHTO-18，最后会发现第二个时间窗口，其中包含正确行的详细信息。
