Question

最近我在eclipse Kelper（4.3.2）中创建了安装了BIRT的报告。

在动态网络项目中，我为客户创建了报告 - 隐私政策 - 无法附加，但很简单。

它有：

1个数据库连接

2个数据集

1格

2桌

1图表

并添加了一些脚本来检查startDate和endDate是否超过31天 - 根据这一点，上面的一些部分将是可见的。

设计时一切正常。甚至＆＃34;查看报告＆＃34;显示的结果让我对完成的工作感到高兴。

但是当我关闭Eclipse时，再次启动它并想要打开报表设计然后没有设计显示 - 只显示有关NullPointerException的信息

enter image description here

我还粘贴日志文件内容。（并非所有因为帖子中的字符限制）

我尝试使用-clean参数运行eclipse，甚至使用干净的eclipse安装（然后创建新的报告项目并粘贴创建的报告），但它没有帮助。

所以看起来问题就在于报告本身..

请你在日志上拿一个战利品？

致以最诚挚的问候，

Answer 1

重新安装BIRT时，您使用的是之前使用的相同工作区吗？如果是这样，那里可能存在腐败。如果是，请尝试定义新工作区或删除旧工作区并从头开始。让我知道。

如果不是这样，您能否通过电子邮件向我发送使用Classic Models Inc示例数据库的示例设计，该数据库向gmail dot com中的mwilliams.actuate显示此问题？感谢。
