我有一个使用 Flex 4.6.0 SDK 的 mx:application 并且仅在 Chrome 中遇到了 FlexPrintJob 的一些问题。FlexPrintJob 在 chrome 中运行良好，直到几周前（我没有对代码进行任何更改），现在我开始经历“冲击波崩溃”。
打印时我正在使用：
- 第一个标题页模板
- 处理 DataGrid 的中间部分模板。这是使用 PrintDataGrid 并循环通过 dataProvider 以查看数据是否适合一页，如果不适合则创建另一页。
- 条款和条件最后一页模板
问题：我已将其范围缩小到这一点，当数据（中间部分）超过一页并尝试创建另一页时，我在 chrome 中收到 Shockwave Crash 错误。这刚刚开始发生，我猜是 chrome 更新……对不起，如果我遗漏了一些东西并且我的描述缺乏细节。如果需要，我可以添加更多说明。
有什么想法吗？
谢谢！
