Issue
Attachments in the knowledge article are not visible in the "kb_article_view" page of the knowledge portal. But the attachments are visible in the articles when opened in native UI(non-portal) and also visible in the "kb_article" page of the Service portal.
Release
Knowledge portal
Cause
On the kb_article_view page, there is a separate widget "Knowledge Attachments" to show the attachment of the article. This widget collects the data such as "tableName", "article_sys_id" from the widget "Knowledge Article Content" widget (which displays the article body). When the user is using the customized "Knowledge Article Content" widget and the "tableName" or the "article_sys_id" is not defined in the same custom widget, the attachment wouldn't be visible.
Resolution
Declare and define the tableName/article_sys_id in the custom 'Knowledge Article Content' widget.
