BZ979: Collection damage reported after Apple events access
Category

Bug

The Problem

Collections used with Helix Server or Helix Engine Preview Release versions 6.1 – 6.1.2 could leave internal data in a state that Update Collection 6.0.x considers wrong, resulting in a false report of collection damage.

Discussion

Helix 6.1 no longer uses the ‘compiled form’ data that was used in Helix 6.0, but Update Collection is not aware of this. In cases where Apple event access users neglected to close a process, this obsolete data would not be cleared properly. Because Update Collection is backward compatible with Helix 6.0, it considers this a problem and reports collection damage. In reality there is no damage; Update Collection is being overly sensitive.

Helix 6.1.3 takes greater care to discard this obsolete data, keeping Update Collection from falsely reporting damage.

Helix 6.1.3 also restores the original limitation of one open Apple event process per licensed seat.

Workaround

To avoid this bug, close all Apple event external access processes before quitting Helix.

Scope

This bug affects Helix Server and Helix Engine Preview Release versions 6.1 – 6.1.2.

Status

This bug is fixed in Helix 6.1.3.
