Customer FAQ related articles do not react to RichText editor changes

[t3it-development]

Summary

FAQ.Customer.RelatedArticles.js registers RichText editor event handlers using old CKEditor 4 event names. The current OTOBO RichText editor uses CKEditor 5, so the handlers for key, paste, and blur are not fired.

As a result, changes in the customer RichText body do not trigger the related FAQ article refresh logic.

Affected File

var/httpd/htdocs/js/FAQ.Customer.RelatedArticles.js

Actual Behavior

When typing, pasting, or leaving the RichText editor in the customer ticket message form:

• no RichText-related console.log output appears
• $('#Subject').trigger('change') is not executed from RichText events
• related FAQ articles are not refreshed based on the updated body content

Expected Behavior

RichText editor interactions should trigger the existing FAQ related article refresh logic:

• key input should be detected
• paste should be detected
• blur/focus loss should be detected
• related FAQ articles should update when the body content changes

Technical Cause

The code uses CKEditor 4 style handlers:

CKEditorInstances['RichText'].on('key', ...)
CKEditorInstances['RichText'].on('paste', ...)
CKEditorInstances['RichText'].on('blur', ...)

But Core.UI.RichTextEditor.js creates a CKEditor 5 ClassicEditor instance. CKEditor 5 requires different event APIs
