KB-XXXX Deleting VERSION_ORIGINAL of a content object causes aberrant behaviour

Symptoms

After deleting content object (Appian expression, interface and constant) versions using the Suite API methods deleteVersion or deleteVersions, the following behaviour is observed:

• The suggestion panel will not show any information for that content when hovering over an invocation of the content in the expression editor.
• Interface configurations and bindings in process models will be lost, and it will not be possible to reconfigure them.

Cause

The VERSION_ORIGINAL version of the content object was deleted. It is not a valid operation to delete this version of a content object, instead, it should be deactivated using the deactivateVersion Suite API method.

Action

Republish the affected content object by either reimporting it, or saving it in the /design interface.

Affected Versions

This article applies to all versions of Appian.
