Hold back on installing OO 5.8.3?

Automation OmniOutliner Automation

A recent OmniOutliner update:

5.8.3 (v206.6.0)

seems to contain a regression which can cause crashes with some scripts.

Some JXA scripts accessing omniJS through the .evaluateJavascript method:

  1. Work fine on 5.8.2
  2. but are crashed by 5.8.3 (v206.6.0)

The regression in OmniOutliner 5.8.3 causes a crash

when a non-string value is returned from an application of the

.evaluateJavascript method.

The code in the following post, evaluated from Script Editor, for example,

crashes (on the return of a value) in OO 5.8.3,

but works fine in OO 5.8.2

This looks like a regression to a value return

crasher which had been fixed in earlier builds.

A JavaScript for Automation (JXA) script,

for evaluation by OmniOutliner.evaluateJavascript(…)
