AEM ACS Commons Generic List editor breaks when more than 8 items are added

ACS Commons version 5.0.6
AEM version 6.5.8.0

I am attempting to edit a Generic List in http://localhost:4502/generic-lists.html/etc/acs-commons/lists by clicking the thumbnail and then clicking the "Properties" in the top action bar. This brings me to http://localhost:4502/mnt/overlay/acs-commons/components/utilities/genericlist.html?item=/etc/acs-commons/lists/[path-to-list]. When there are 8 or fewer items already configured in the generic list, the editor page loads as expected and I can update the list. When there are greater than 8 items, a blank page is loaded and I get the following stack trace in my error log:

Has anybody experience this issue before? The issue has been raised in GitHub for the ACS Commons project, but no solution has been discovered to my knowledge.

Solution

  • As per my experience this issue happens due to rewriter configurations . Please try removing /apps/myapp/config/rewriter and check if it works fine.
