Vaadin 表什么也没显示
我有一个 vaadin 表，我在其中使用某些过滤器进行过滤，就像在地址簿示例中一样（+我添加了更多）。有时，现在表看起来是空的，没有标题。
之前有标题和项目。不仅仅是项目全部被过滤掉，在调试时我看到表附加的容器仍然包含项目，并且过滤的也不为空。有人已经克服了这个问题吗？
非常感谢任何如何解决的提示。
I have a vaadin table where I use certain filters for filtering, just like in the addressbook example (+ I added some more). Sometimes now it occurs that the table looks empty with NO HEADERS.
There were headers and items before. It is not just that the items are all filtered out, when debugging I see that the container the table is attached to still contains the items, and filtered is also not empty. Has anyone overcome that problem already?
Any hints how to solve are very appreciated.

您可能使用的是 Vaadin 6.7.0。该版本有一个回归，其中将项目添加到具有带集合的显式列。如果将
?debug附加到 URL，您将在调试窗口中看到错误。该错误已在已发布的 Vaadin 6.7.1 中得到解决。You are probably using Vaadin 6.7.0. That version has a regression where a Javascript error occurs when adding an item to an empty table that has an explicit column with set. If you append
?debugto the URL, you will see the error in the debug window. That bug is resolved in Vaadin 6.7.1 which has already been released.
