添加超过 8 个项目时，AEM ACS Commons 通用列表编辑器会中断

2024-03-11

ACS 共享版本 5.0.6
AEM 版本 6.5.8.0

我试图通过单击缩略图，然后单击顶部操作栏中的“属性”来编辑 http://localhost:4502/generic-lists.html/etc/acs-commons/lists 中的通用列表。这将我带到http://localhost:4502/mnt/overlay/acs-commons/components/utilities/genericlist.html?item=/etc/acs-commons/lists/[path-to-list]。当通用列表中已配置 8 个或更少的项目时，编辑器页面将按预期加载，并且我可以更新列表。当项目超过 8 个时，将加载一个空白页面，并且我在错误日志中收到以下堆栈跟踪：

以前有人遇到过这个问题吗？该问题已在 ACS Commons 项目的 GitHub 中提出，但据我所知尚未发现解决方案。

根据我的经验，此问题是由于重写器配置而发生的。请尝试删除 /apps/myapp/config/rewriter 并检查它是否正常工作。
