我有一个运行良好的水晶报告，直到我在 Firefox 中对其进行了测试。它在第一次加载时显示数据/报告，但是当我单击报告过滤器的“开始”按钮时，它会显示空白报告，除非我单击这些按钮中的任何一个 - 放大、缩小、页面/浏览器刷新并输入页码。这只发生在 Firefox 中。Chrome 和 IE 加载它就好了。顺便说一句，我正在使用 site.master 页面。
我尝试了什么：
- 隐藏的报告标题
- 取消选中报告中的“新页面”复选框
- 确保在调试中报告源中有项目。它有特别的。单击刷新时，它会再次显示报告。另外，我将空白报告导出到excel，它确实有数据
可能是什么原因造成的？有什么建议吗？
