CMS 10.6.378: Nested Categories with 30+ Siblings Not Displaying as Selected in Taxonomy Tree

Statement of Issue

When you select a category in Administration > Taxonomy, CMS 10.6.378 does not highlight your selection if the category has approximately 30 to 35 or more siblings and is nested under a child category. This issue prevents you from viewing the full list of categories in the Taxonomy Tree.

Symptoms

Selecting categories that have approximately 30 to 35+ siblings and are nested under a child category throws the following console error:

ERROR TypeError: Cannot read properties of undefined (reading 'find')

    at callHooks (vendor-es2015.js?cmsVerion=10.6.378:176905:17)

This error prevents the CMS from displaying the category as selected in the Taxonomy Tree.

Resolution

Workaround

As a CMS 10.6.378 workaround, system administrators can deploy a patched version of the main-es2015.js file to the CMS file system.

To deploy the patched main-es2015.js file, complete the following steps:

1. Download main-es2015_PATCHED.js to the CMS server.
2. Rename main-es2015_PATCHED.js to main-es2015.js.
3. Replace the old main-es2015.js file with the new one of the same name in [Drive:]\[path-to-cms-site-instance]\js\ngDist.
4. Recycle the CMS instance application pool by completing the following steps:
   1. Open Internet Information Services Manager (IIS), then navigate to the CMS instance's application pool.
   2. Right-click the application pool, and click Recycle.

After the application pool recycle completes, navigate to Administration > Taxonomy and select categories in the Taxonomy Tree.
