In the end, in my .content.xml files, I put lodash.underscore instead of underscore and that worked to fix my Dialog errors. I think the "underscore" was removed in 6.5.10 but you can still use the lodash.underscore.

Hi, I was wrong about the acs-commons-old causing my problems, On further examination it was this.....   https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/after-updating-aem-6-5-10-underscore-dependency-is-not-loading/m-p/426336#M121452   So I must add a library "underscore" ...

Hi, I got rid of the dud duplicate library, but I still had my Dialog save problem. On further examination, I finally figured that the Dialog code that was breaking was using underscore. So I found this.   https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/after-updating-aem-6...

Hi folks, I have this problem also. I don't have visibility of Prod crx/de so I don't know what exactly is there after the upgrade to 6.5.12.   I'm confused about the solution. Should I 1.

She may have made a copy of acs-commons during the 6.5 upgrade a few years ago? But I don't see anything like that in the...

hi ! I posted another clearer Question as I think that the multifield problem  is just a symptom of the old and new libraries getting muddled up. In the end, in my .content.xml files, I put lodash.underscore instead of underscore and that worked to fix my Dialog errors. thanks Fiona   https://experi...

hi folks, This happened after a recent upgrade to 6.5.12 from 6.5.5. It doesn't happen on lower environments where only /apps/acs-commons is used. According to my Package Mgr, acs-commons 4.11.0  apps and content are installed on Prod which looks the same as the lower environments.   thanks in advan...

The acs commons version is 4.11.0 I don't have acs-tools there.   The multifield component that is giving trouble  is modified locally as follows   <%@ page import="com.adobe.granite.ui.components.Confi...
