birt不会保存数据集，出现“结构无效”错误
提问于 2014-03-11 05:10:42
我们正在尝试在重新创建数据库后更新BIRT report项目。所以我输入了新的查询，但是当我移动到Parameters选项卡(或任何选项卡)时，出现以下错误：
The structure is floating, and its handler is invalid!
弹出，并在错误日志中显示以下错误：
Problems occurred when invoking code from plug-in: "org.eclipse.jface".
在此之后，其他内容都不起作用；更改不会注册(选项卡中的库名旁边没有星号)，并且我不能保存任何内容。
堆栈跟踪：

我不知道要搜索什么；我找到的所有结果都来自不同的错误。从"-clean“开始不起作用，重新创建BIRT报表项目也不起作用……任何在正确方向上的推动都将是足够的帮助。
问候你，Cez

我得到了同样的错误，但执行下面的步骤帮了我的忙。(我正在处理一个表)
- Delete the data sets
- 选择该表，在属性编辑器选项卡下，单击binding选项卡，选中Data set并选择none。
- 您应该会看到一个提示，询问您是否要清除所有现有数据字段信息，请单击‘yes’。
所有引用已删除数据集的数据绑定现在将被清除，瞧…继续你的工作。让我知道这是否也适用于你。
