java.lang.ClassCastException 当最大化 mpart
java.lang.ClassCastException when maximize mpart
我有一个带有一些不同 MPart 的 Eclipse E4 应用程序。现在，当我通过双击选项卡最大化 MPart 时，我得到了 ClassCastException。同样，当我再次最小化它时，将抛出相同的异常。我查看了错误，但在我的源代码中找不到可以抛出此异常的位置。有人可以帮我弄这个吗？您可以在下面找到错误的完整堆栈跟踪。

我发现了问题。一些旧代码仍在我的 class 中用于绘制 Nattable。
代码是一个 GridFactory，它将 table 放在网格上。删除此行解决了我的问题。
我有一个带有一些不同 MPart 的 Eclipse E4 应用程序。现在，当我通过双击选项卡最大化 MPart 时，我得到了 ClassCastException。同样，当我再次最小化它时，将抛出相同的异常。我查看了错误，但在我的源代码中找不到可以抛出此异常的位置。有人可以帮我弄这个吗？您可以在下面找到错误的完整堆栈跟踪。
